 The baby-faced 19-year-old turned himself in to a Toronto police station Wednesday evening, arriving amid a crush of media and screaming fans. He was charged with one count of assault and is scheduled to appear in court in Toronto on March 10. 
 
 Police allege Bieber was one of six people who were picked up by a limousine from a nightclub in the early morning hours of Dec. 30, and there was an altercation while en route to a hotel. 
 
 Police said that, during the altercation, one of the passengers hit the limo driver in the back of the head several times. 
 
 "The driver stopped the limousine, exited the vehicle and called police," a statement said. "The man who struck him left the scene before police arrived." 
 
 Howard Weitzman, Bieber's attorney in California, said his client is innocent and declined to comment on the allegations against Bieber or any potential defense, saying it was now a matter for the court to handle. 
 
 Weitzman said he expects the case to be treated as a summary offense, which is the equivalent of a misdemeanor in the United States. "The Toronto Police Service requested that Justin Bieber appear in Toronto today to face an allegation of assault relating to an incident on December 29, 2013. We anticipate that this matter will be treated as a summary offense, the equivalent of a misdemeanor in the United States," he said in a statement. 
 
 Brian Greenspan, Bieber's Canadian attorney, did not immediately return a message seeking comment. 
 
 Toronto police said in late December they were looking into allegations that a member of Bieber's entourage assaulted a limo driver who was ferrying the Canadian pop star and several others. Police said at the time it was unclear whether Bieber was involved. 
 
 Bieber emerged from a black SUV wearing a winter coat and a backwards ball cap before being led through a throng of police and reporters. Many waited for his arrival for more than an hour in freezing temperatures. 
 
 He was escorted by several police officers — who linked arms to guide him through the mob — and a bodyguard, reports the Canadian Broadcasting Corporation (CBC), a CBS News partner. 
 
 Bieber spent about an hour and a half in the police station before leaving through a back exit. 
 
 It was yet another sign of the crazy lifestyle that has taken over Bieber's image. 
 
 Earlier on Wednesday, Bieber pleaded not guilty in Florida to charges of driving under the influence after allegedly driving nearly twice the speed limit on a Miami Beach street. He also pleaded not guilty to resisting arrest and driving with an expired license. 
 
 Court records show that Bieber's attorney filed a written plea in Miami-Dade County. Bieber already has an arraignment set for Feb. 14, but Florida law doesn't require the 19-year-old pop star to be present. 
 
 Bieber and R&B singer Khalil Amir Sharieff were arrested last week in Miami Beach during what police described as an illegal street drag race between a Lamborghini and a Ferrari. Neither has been charged with drag racing, which is a crime in Florida. 
 
 According to the CBC, "Bieber's blood-alcohol level in the Miami incident wasn't released. Under Florida law, people under the age of 21 are considered driving under the influence if they have a blood-alcohol content of 0.02 or more — a level the 5-foot-9, 140-pound star could reach with one drink." 
 
 The Canadian pop star lately has drawn more attention for his brushes with the law than for his music. 
 
 His arrival at the Toronto police station was no different - the singer debuted a music video for his song "Confident" on Wednesday afternoon, just as news of his expected arrest was breaking. 
 
 Bieber remains under investigation for felony vandalism in Los Angeles County over an egg-tossing episode that did $20,999 in damage to his neighbor's home. Detectives searched his home on Jan. 14, seeking surveillance video, and prosecutors have sought additional information before determining whether to pursue charges. 
 
 No charges have been filed in that investigation, but one of Bieber’s house guests, rapper Lil Za, was arrested when deputies allegedly found illegal drugs during their search. 
 
 Bieber's antics have prompted more than 115,000 people to sign a WhiteHouse.gov petition demanding that the star be deported to his native Canada. Because the petition has topped 100,000 signatures, the Obama administration must respond to it. 
 
 The cases have overshadowed the recent release of his latest album. Its reception has been far from the chart-topping success Bieber had after he debuted in 2009, with multiple platinum albums. 
 
 Last year, Bieber made headlines for everything from clashing with a paparazzo to fainting at a show to being photographed smoking marijuana. The paparazzo is suing Bieber for assault and battery. 
 
 German authorities charged him thousands of dollars after he abandoned a pet monkey that they seized from him for failing to have proper vaccination papers. 
 
 The singer also had to apologize to Bill Clinton after cursing the former president and spraying his photo with cleaning fluid in a New York City restaurant kitchen. 
 
 Bieber was discovered through a YouTube video of him performing, and his career has been guided by a pair of music industry heavyweights, singer Usher and manager Scooter Braun. He has been nominated for two Grammy Awards for his 2010 full-length album debut "My World 2.0," but his popularity has waned. 
 
 Braun tweeted Wednesday evening, "i ask people to be kind and hope for the best in people. not assume the worst. Thanks." 
 
 Jon Bollock, a 14-year-old fan waiting for Bieber to arrive outside the Toronto police station, said he wanted to see Bieber but said "it's pretty embarrassing for Canada." ||||| (CNN) -- Justin Bieber was under the influence of alcohol, pot and Xanax when police stopped him for drag racing in Miami Beach last week, police documents allege. 
 
 "Yeah, we were smoking all night at the studio," the singer told a police officer who told him he "reeked of marijuana," according to documents released Thursday. 
 
 Bieber was "excited," "talkative," "insulting" and "cocky" and "used profanity," according to a intoxication evaluation conducted by police in the Florida city. 
 
 His speech was mumbled, his pupils dilated, his face flushed and his eyes bloodshot, the assessment said. 
 
 The lab test results and details of Bieber's sobriety tests were released just hours after the 19-year-old singer was booked on an assault charge in Canada, accused of hitting his limousine driver in Toronto a month ago. 
 
 Bieber, who will turn 20 in four weeks, apparently sought refuge Wednesday night in Stratford, the Canadian town where he grew up before becoming a pop star. 
 
 His father tweeted a photo of Bieber asleep in a bed with Justin's younger half brother, Jaxon. The Twitter message posted by @JeremyBieber read: "Safe and sound #homesweethome" 
 
 Earlier Wednesday, Bieber's lawyer entered a "not guilty" plea to the Florida charges of DUI, resisting arrest and driving with an expired license, according to court records. 
 
 The prospect of a third criminal arrest for Bieber hangs on a decision expected as soon as next week, after detectives investigating an alleged egg attack on his California neighbor meet again with a Los Angeles prosecutor. 
 
 Bieber told police in Miami Beach that he had taken "medications for anxiety" that night but that he did not know what it was or whether he had a prescription for it. "Well, my mom takes care of all that stuff for me," the police report quoted him as saying. 
 
 The preliminary toxicology report on Bieber's urine sample said it tested positive for "metabolite of THC," which indicates marijuana use, and alprazolam, the generic name for the prescription sedative Xanax. 
 
 At the police station, Bieber failed a series of sobriety tests, including "horizontal gaze," "Romberg balance," "walk and turn," "finger to nose" and "one-leg stand" tests, the police report said. 
 
 When Bieber was asked to estimate when 30 seconds passed, he failed by thinking a half-minute was over in 17 seconds, the report said. 
 
 He had "great difficulty" completing the Breathalyzer test, the officer wrote. He "continuously forgot basic instructions." 
 
 Bieber told the officer "that he was blowing as hard as he could, and told me to look at how red his face was," he wrote. "He advised he was blowing into the hose like he blows into his trumpet." 
 
 When he was finally successful, he blew .011 and .014 in two Breathalyzer tests, the report said. Florida's legal limit for drivers under the drinking age of 21 is .02. 
 
 Bieber was briefly jailed in Miami Beach on January 23 after he was stopped by a police officer who said he was drag racing in a Lambourghini on a residential street.

 Toronto assault charge 
 
 Bieber arrived at a Toronto police station for booking Wednesday evening amid a chaotic scene as determined photographers, reporters, screaming fans and the curious converged around his SUV. About a dozen Toronto police officers shoved their way through the crowd to escort Bieber, getting him through the door only after a struggle. 
 
 The alleged incident happened after the limo driver picked up a group of six people outside a Toronto nightclub just before 3 a.m. December 30, according to a police statement. 
 
 "While driving the group to a hotel, an altercation occurred between one of the passengers and the driver of the limousine," the police statement said. "In the course of the altercation, a man struck the limousine driver on the back of the head several times. The driver stopped the limousine, exited the vehicle and called police." 
 
 The singer attended a Toronto Maple Leafs hockey game at the Air Canada Centre earlier in the evening, according to the CBC. 
 
 Bieber left the Toronto police station through a rear exit after about two hours inside Wednesday night. He is set to appear in a Toronto court on March 10, police said. 
 
 Bieber's Los Angeles lawyer said the charge was "the equivalent of a misdemeanor in the United States." 
 
 "Our position is that Mr. Bieber is innocent," attorney Howard Wietzman said. "As the matter is now before the court, it would be inappropriate to address the specifics of either the allegation or of our defense at this time." 
 
 Bieber's manager, Scooter Braun, posted messages on Twitter that appear to be related to Wednesday's arrest: 
 
 "for all those asking @JeremyBieber and @pattiemallette love their son. Stop passing judgement on a situation u dont understand. i ask people to be kind and hope for the best in people. not assume the worst. thanks" 
 
 Bieber's latest criminal arrest came just an hour after the television debut of his newest video, for his song "Confident."

 Egging investigation 'tightening up' 
 
 Detectives are "tightening up" their case against Bieber in his alleged egg attack on a neighbor's residence, an investigator said Tuesday. 
 
 The neighbor accused Bieber of tossing eggs over a fence and onto the mansion next door on January 9, causing an estimated $20,000 in damage. 
 
 A dozen Los Angeles County Sheriff's deputies raided Bieber's $6.5 million home in the exclusive Oaks community in Calabasas, California, two weeks ago, taking the security video system as evidence. 
 
 A prosecutor reviewed the security video Monday and asked detectives to do more investigation before a decision is made about charging the pop star with felony vandalism, according to Lt. David Thompson. 
 
 Detectives will probably meet again with prosecutors in the Los Angeles County District Attorney's office next week, Thompson said. The district attorney will then decide whether a charge will be filed against Bieber.

– Yet more criminal trouble for Justin Bieber: He turned himself in at a Toronto police station last night, where he was charged with assault and then quickly released, CBS News reports. Police say Biebs and five other people had a limousine pick them up at a nightclub in the city in the wee hours of Dec. 30 (Bieber had earlier attended a Toronto Maple Leafs hockey game, CNN reports), but there was some sort of fight as they were being driven to a hotel. One of the passengers hit the limo driver in the back of the head multiple times, police say, and then left the scene before police got there. It didn't help his case that Bieber failed to show up for a police interview after the incident, reports TMZ, which claims that Bieber, and not a member of his entourage, is the one suspected of actually assaulting the driver. His first court appearance is scheduled for March 10. The assault charge came just hours after his lawyer entered a not guilty plea for Bieber in his DUI-and-drag-racing case from last week (an arraignment is set for Valentine's Day), and he's still facing possible charges over the egging of his neighbor's house. Evidence was presented to the district attorney in that case this week, CNN reports, but prosecutors asked detectives to investigate further. A decision on whether to charge Bieber with felony vandalism could be made by next week. (Not surprisingly, lots of Americans want to see Bieber deported.)
