Prosecutors to revoke Chris Brown's probation

The center is an hour's drive from Richmond, and the prosecution motion says a detective checked on Brown on only nine occasions when he was working there. Each time, the singer was found at the center, accompanied by his mother and a bodyguard but no law enforcement personnel.

The hours Brown recorded as working at the center were done overnight when children were not present. Some of the records stated Brown waxed floors or did "general cleaning".

"Claims that the defendant cleaned, stripped and waxed floors at that location have been credibly contradicted," the prosecution motion states. A professional floor cleaner contracted to work at the daycare center told investigators he had been cleaning the floors throughout the months Brown reported working at the facility.

Brown's mother, Joyce Hawkins, no longer had a formal role at the Tappahannock Children's Center but had her own set of keys and coordinated her son's work at the facility, the motion states.

The filing also alleges Brown violated his probation with several violent outbursts that haven't resulted in arrests or charges. In addition to the fight between Brown and Ocean, the motion cites a 2012 incident in Miami in which Brown was accused of taking a woman's cellphone and the March 2011 incident in which Brown threw a chair through a window after appearing on "Good Morning America".

Brown and Ocean are both nominated for the Best Urban Contemporary Album category at Sunday's Grammys. Ocean, who has said his first love was a man, told authorities that someone may have shouted a gay slur during the fight, but he wasn't sure.

Ocean suffered cuts on his right index finger and minor cuts to his left temple.
