They were trying to bring home the bacon. 
 
 A group of burglars — at least one of whom was seen wearing a pig mask and wielding a sledgehammer — broke into a Rolex store inside of a legendary Las Vegas casino early Saturday, police and witnesses said. 
 
 Scores of police officers decked out in tactical gear were seen in videos and photos posted to social media rushing to the Bellagio casino shortly after midnight, as reports of an active shooter streamed in over Twitter. 
 
 The high-end resort was on lockdown for roughly half an hour, ABC News reported.

 But a Las Vegas police spokesman later dismissed the shooting report, instead confirming that there was an armed robbery inside the high-priced jewelry store, which is in the lobby. A preliminary investigation suggested that at least three robbers used a sledgehammer to break in, the spokesman added. 
 
 While police said no one was injured, witnesses recounted a chaotic scene inside the casino. 
 
 A 21-year-old California woman — who only identified herself as Kira — told the Daily News that she had just gotten out of the bathroom when she spotted a stocky man wearing all black standing guard outside the Rolex store.

 To Kira’s shock, the man wielded a handgun — and wore a pink pig mask.

 “He was screaming at people, pointing his gun, making sure that anyone who was close just got away,” Kira said over the phone, adding that the pig-headed man repeatedly shouted “Get out! Get out!”

 Once outside, Kira said she saw the same man being led away by police, but no longer sporting his swine disguise. 
 
 Cops told the Las Vegas Sun that the suspects tried to flee in their car, but it wouldn't start when they found it in the parking lot. They tried to steal another car, and that also didn't pan out. They then tried to get away on foot, police said.

 Chris, a 50-year-old Las Vegas native, was playing poker upstairs when he thought he heard gunshots ring out. 
 
 “I ran around the corner and I heard two shots, ‘bang, bang,’” Chris told The News. “When I looked back, everything was already chaos.” 
 
 People began running for the doors, and some gamblers got trampled in the commotion, Chris said.

 “You'd never think of anyone bringing a gun in here,” said Chris, a self-described professional poker player. “It's like old Wild West stuff. But you know, Vegas, it's all types of stuff that happens here.”

 One suspect is in custody and the investigation is continuing following the robbery of the store at Bellagio Resort & Casino overnight on Friday, Las Vegas Metropolitan Police detectives said Saturday. 
 
 Detectives also said earlier reports of shooting during the burglary were unfounded, and they now believe the sound of sledgehammers striking the jewelry cases were mistaken for gunfire. 
 
 When police descended upon the resort and casino in response to the burglary, guests fled in panic from the property, flooding surrounding streets, amid false reports of an "active shooter." 
 
 "Currently investigating burglary at @bellagio," the Las Vegas Metropolitan Police Department tweeted at 2:13 a.m. "Initial reports indicated there was an 'active shooter' which was false. NO injuries."

 Although there was no shooting during the incident, the robbers were armed, the Las Vegas Metropolitan Police Department's Lt. Carlos Hank told ABC News. 
 
 The Bellagio was on lockdown after the incident for about 30 minutes. 
 
 The store was not open at the time of the incident. 
 
 The suspects wore character masks, but Lt. Hank could not confirm the specifics of the mask. One eyewitness, though -- a woman named Kira, who did not want her surname used -- told ABC News she saw a man wearing a pig mask (below).

 Lt. Hank said early Saturday morning that some people were detained, but it is unclear if the detained individuals are burglary suspects.

– "It is like a movie—it's crazy," Lt. Carlos Hank tells the Las Vegas Review-Journal. Early Saturday, at least three people in "dark, nice suits" and animal masks entered the Bellagio in Las Vegas and ripped off a "high-end retail store." One witness describes seeing a man wearing a pig mask and holding a gun standing guard outside a Rolex store while his compatriots used a sledgehammer to break the glass. “He was screaming at people, pointing his gun, making sure that anyone who was close just got away," she tells the New York Daily News. The sound of the breaking glass led to false reports of gunshots and chaos inside the casino. The masked men grabbed items from the store and ran off while ditching their fancy duds. Police detained several people for questioning, but ABC News reports police aren't confirming if those detained are suspects. The Rolex store was closed at the time of the incident, but the Bellagio was placed on lockdown for about half an hour afterward. No injuries were reported. “It's like old wild west stuff," a professional poker player tells the Daily News. "But you know, Vegas; it's all types of stuff that happens here.”
