Akron, Ohio police are investigating a woman’s complaint that she was sexually assaulted on Waka Flocka Flame‘s tour bus.

According to the Cleveland Plain Dealer, the complaint isn’t against Waka Flocka himself, but that it occurred on his bus.

“We have a sexual assault complaint, but nothing has been determined yet,” said Lt. Rick Edwards.

The bus was boarded by Akron detectives in response to the woman’s call, which occurred at 2:50 AM on Monday (July 12).

The rapper was in Ohio for WENZ FM/107.9’s Summer Jam, which also included Rick Ross, Plies, Trina, Teirra Mari, Roscoe Dash and others.
