Richmond police spokesman Gene Lepley declined to discuss the allegations.
‘‘We believe it would inappropriate to comment on a matter that’s before the court,’’ Lepley said.
According to the motion, officials with Virginia’s probation office told investigators that Brown’s arrangement to be supervised by Norwood was ‘‘extremely unusual’’ and had not been approved by the agency. No one from Virginia’s probation department oversaw Brown’s hours, prosecutors said.
The motion noted that the only records the department has to indicate Brown was supervised were officers’ overtime sheets. Five of 21 days that officers logged overtime for Brown were spent providing security for the singer’s concerts.
The allegations are the latest pre-Grammy controversy for Brown, who was arrested shortly after the 2009 ceremony for his attack on Rihanna. He has since returned to the awards show by performing and winning an award in 2011 for his album ‘‘F.A.M.E.’’
Brown and Ocean are competing against one other for the Best Urban Contemporary Album category at Sunday’s Grammys.
