Los Angeles ( CNN ) -- A judge revoked Chris Brown 's probation because of his October arrest in Washington , but the singer 's not going to jail because he 's already in a court-ordered residential rehab program . Brown , who appeared before a Los Angeles County Superior Court judge Monday , must return for a hearing on February 10 that will decide if he 'll serve jail time after his three months in rehab . The singer has an anger-management problem and drug-abuse issues , according to a probation report obtained by CNN . He 's been on felony probation since pleading guilty to beating up singer Rihanna on the eve of the Grammys in 2009 . Judge James Brandlin ordered Brown to check into a rehab program a month ago after he had been booted from another rehab facility a week earlier for smashing his mother 's car window during a family session . A report submitted to the judge by Brown 's probation officer included a letter from his current rehab facility saying he `` has made significant progress '' since starting in the program on November 20 . Brown kicked out of rehab for 'acting violently , ' ordered to new facility . `` The clinical and medical team have witnessed very positive change in Mr. Brown since his psychotropic medications have been changed and he has been taken off medical marijuana , '' the program director said . `` His ability to emotionally regulate himself has improved markedly . '' `` I 'm pleased that he 's doing well , '' Brandlin said Monday , explaining why he did not send him to jail Monday afternoon . Brown was arrested on an assault charge in Washington on October 27 . That case is why Brandlin ruled Monday that he was tentatively revoking Brown 's probation for the Rihanna assault . He will decide in February if he will order Brown to complete his sentence in prison instead of probation . Brown 's girlfriend Karrueche Tran accompanied him to the Los Angeles County courtroom Monday . For the second time , his mother was not with him . Brown 's freedom has been in question since he was arrested on a sidewalk near the White House after allegedly punching a man . The probation imposed when he pleaded guilty to a felony charge in the attack on Rihanna -- his girlfriend at the time -- requires that he stay out of legal trouble . Brown voluntarily entered a rehab center on October 28 , a day after he was released from a Washington jail . Secret Service report could help Chris Brown 's defense . The probation report given to the judge last month revealed that he was kicked out of the program . It quoted a center official saying he was ordered out for `` breaking program rules by acting violently . '' The violence involved Brown `` throwing a rock through his mother 's car window '' after a family session at the center in which she said she wanted him to stay in treatment . `` Mr. Brown preceded to walk outside and pick up a rock and threw it through his mother 's car window and it shattered , '' according to letter from the rehab center included in the probation report . Brown 's `` prognosis is very guarded '' unless he gets professional help , the letter said . Brown leaves the new rehab center three days a week to work eight-hour shifts of community labor so that he can complete the 1,000 hours of work still remaining in his punishment for attacking Rihanna . The report estimated he will have to work on community labor three days of every week until next August to meet the deadline for completing the labor . He may also travel to Washington for a court hearing on January 8 in the assault case there , the judge said .
