Los Angeles ( CNN ) -- Rihanna left no doubt about how she feels about Chris Brown and the probation he 's serving for beating her up four years ago . The pop star sat behind Brown in court Wednesday while a prosecutor asked a judge to order the singer to restart the community labor that is his punishment for the felony assault conviction . It was Rihanna 's second time in a courtroom with Brown . The first was the day in August 2009 when Brown was sentenced to five years ' probation and ordered to stay away from her . Then , she was a witness for the prosecution . `` She thinks it 's utterly ridiculous what they 're doing to him , '' Brown lawyer Mark Geragos said when a reporter asked why his assault victim was in court . The Los Angeles County district attorney 's office has `` tortured '' Brown during his probation worse than any client he 's ever had , Geragos said . In a court filing this week , prosecutors accused Brown of not completing the 180 days of community labor ordered when he pleaded guilty to the felony assault charge . The paperwork Brown submitted to show he had completed community labor is `` at best sloppy documentation and at worst fraudulent reporting , '' District Attorney Jackie Lacey said . Brown was n't in town on some of the dates reported , the motion said . Geragos , however , angrily disputed the charges , calling them `` absolutely false . '' `` And I do n't mean just false , it is fraudulent , '' Geragos said after the hearing . Brown 's attorney said the prosecutor 's filing was so fraudulent that he would ask the judge to punish the deputy district attorneys involved and call for a contempt of court hearing for filing false documents with the court . Los Angeles County Superior Court Judge James Brandlin set a hearing for April 5 for Brown to return to court , but a full hearing on the allegations will be held later . The ever divisive Chris Brown . Brandlin ordered Brown to report to his probation officer within the next two days to be interviewed for a report that will be used at the hearing . Despite the serious allegations outlined in the court filing , the prosecutor is not asking for Brown 's probation to be revoked and the singer sent to jail . She is asking the judge to order him to restart his 1,400 hours of community service under the supervision of a Los Angeles probation officer . Brown got an unusual deal when he pleaded guilty that allowed him to complete his court-ordered community service in Virginia , under the personal supervision of Richmond Police Chief Bryan Norwood . Normally , community service must be supervised by a probation office . The district attorney alleged that investigators he sent to Virginia discovered that Brown 's mother supervised most of it , and they found evidence it was never done . In response , Geragos said he 's received 10 e-mails in the past day from Richmond police officers and firefighters `` who observed Chris doing his community service . '' `` I 've got pictures , I 've got witnesses , '' Geragos said . `` I 've got what they do n't have . We have evidence that he did it . '' The motion also accused Brown of violating probation by punching singer Frank Ocean at a Hollywood recording studio last month , threatening to `` bust '' -- or shoot -- the singer . It also notes a Miami incident during which Brown allegedly stole a fan 's cell phone and a chair-throwing incident after a `` Good Morning America '' interview . Also , Brown 's claim to have medical marijuana license , which used to defend against a drug test result , was invalid because the acupuncturist who wrote it was not licensed to prescribe drugs , the motion said . This Friday marks the fourth anniversary of the night Brown punched Rihanna inside a rented Lamborghini on a Hollywood street , leaving her face bruised and bloody . Rihanna and Brown broke up after he was arrested for assaulting her , but they 've made no secret in recent months that they are a couple again .
