(CBS) LOS ANGELES - Prosecutors filed paperwork Monday to revoke singer Chris Brown's probation stemming from a 2009 domestic abuse conviction involving his ex-girlfriend Rihanna, CBS Los Angeles reports.
The request comes after Brown was charged last month with misdemeanor hit-and-run and driving without a valid license stemming from a May 21 accident near Toluca Lake.
Brown is accused of rear-ending a Mercedes and then refusing to give the other driver his license. He also allegedly provided the driver with fake insurance information before leaving the scene. He could face six months in jail for each offense in that incident.
The 24-year-old was scheduled to appear in downtown Los Angeles court Monday afternoon for the probation hearing in the case involving singer Rihanna.
After pleading guilty in 2009, Brown was sentenced to five years of probation, which requires him to obey all laws. He was also sentenced to domestic violence counseling and 180 days of community service.
According to the station, his community service hours are also being questioned. According to court documents, while Brown was supposed to be completing his community service in Virginia, he was actually on vacation in Mexico and at one point, was at a charity event in another state.
The Los Angeles District Attorney may also reportedly ask the judge to order Brown to redo all 180 days of his community service in Los Angeles.
If Brown's probation is revoked, he could be sentenced to four years behind bars, the station reports.
