LOS ANGELES , California ( CNN ) -- Pop singer Chris Brown was sentenced Tuesday to serve five years probation and to spend more than 1,400 hours in `` labor-oriented service '' for assaulting his pop star girlfriend , Rihanna . Chris Brown received an expected sentence on Tuesday of probation and community service . Also Tuesday , CNN obtained a probation report for Brown that says the pair were involved in at least two other domestic violence incidents before the February attack for which Brown was sentenced . The probation report , which CNN obtained after Brown 's sentencing , was used to reach his plea agreement . Brown , 20 , was arrested after an early morning argument inside a rented Lamborghini on a Hollywood street on February 8 . Watch Brown get sentenced to probation » . Police investigating the February 8 attack `` learned of two earlier incidents related to domestic violence that went unreported , '' the probation report said . `` The first incident occurred in Europe about three months before the present offense , '' the report said . `` The victim [ Rihanna ] and the defendant [ Brown ] were involved in a verbal dispute and the victim [ Rihanna ] slapped the defendant [ Brown ] . He responded by shoving her into a wall . '' Another incident happened in January , three weeks before the Hollywood incident , when Brown and Rihanna were visiting her home country of Barbados , the report said . `` The defendant [ Brown ] and the victim [ Rihanna ] were visiting Barbados and were driving a Range Rover loaned to them by a local dealership , '' the investigator wrote . `` They had an argument inside the car . The defendant [ Brown ] exited and broke the front driver and passenger side windows of the car . '' At Tuesday 's sentencing , Los Angeles Superior Court Judge Patricia Schnegg said she wants to see Brown do `` actual physical labor , as opposed to some type of community service . '' The sentencing was delayed earlier this month because documents detailing Brown 's proposed community service plan in Virginia , where he maintains a legal residence and wants to serve his sentence , had not arrived in time for Schnegg to review . Brown 's probation will be overseen by the state of California , the judge said . Brown must also complete domestic violence counseling . Schnegg also put a restraining order in place , requiring Brown to stay 50 yards away from Rihanna , 10 yards if the two are at the same industry event . The judge issued a strict warning to Brown not to violate the order , which remains in place until 2014 . Rihanna 's attorney , Donald Etra , would not say whether she wanted the restraining order lifted , but if Rihanna wants the order modified she must personally appear in court to request it , Etra said . Rihanna , whose real name is Robyn Rihanna Fenty , did not attend Tuesday 's sentencing . Watch Brown arrive for sentencing » . According to Brown 's probation report , the February argument began over an incident at a Beverly Hills party . An earlier , sworn statement by Los Angeles Police detective DeShon Andrews said the incident began when Rihanna found a text message on his cell phone from `` a woman who Brown had a previous sexual relationship with . '' The pair argued while in a sports car driven by Brown , the police statement said . It went on to describe the assault in great detail , saying Brown punched Rihanna -- identified in the statement as Robyn F. -- numerous times and put her in a head lock , restricting her breathing and causing her to start to lose consciousness . He threatened to beat her and kill her , according to the statement , and he bit her ear and her fingers . Eventually , the statement said , `` Robyn F. began screaming for help and Brown exited the vehicle and walked away . A resident in the neighborhood heard Robyn F. 's plea for help and called 911 , causing a police response . An investigation was conducted and Robyn F. was issued a domestic violence emergency protective order . '' The detective said Brown sent a text message nine days later , apologizing . Rihanna 's injuries included cuts and bruises inflicted by a large ring on Brown 's right hand , which he used to punch her , the probation report said . `` Officers at the scene observed numerous contusions and abrasions to the victim 's face and forehead , as well as bruising to her left arm near the bicep , '' it said . `` They also saw abrasions to her arms near both wrists and on her upper chest near her collarbone and around her neck . There were abrasions on her left leg and on the inside of her upper lips . '' Rihanna declined to speak to the probation investigator , so the probation report 's details were gathered from police detectives who interviewed her soon after the attack . `` He beat me up , '' Rihanna told the police , the report said . Brown made a public apology last month in a video statement posted on his personal Web site . `` I have told Rihanna countless times , and I 'm telling you today , that I 'm truly , truly sorry in that I was n't able to handle the situation both differently and better , '' Brown said . `` What I did was unacceptable , 100 percent . I can only ask and pray that you forgive me . Please . ''
