Chris Brown was arrested in October after allegedly assaulting a man who photobombed a picture Brown was taking with fans at four in the morning in Washington, D.C. Brown last week rejected a plea deal in the case, and now some discrepancies in the police report have caused D.C. police to launch an internal investigation into the details recorded at the scene.

According to the Associated Press (via Billboard), an acquaintance of Brown's who was at the scene was told by a police officer that the victim in the incident had told the police that Brown was not the one who hit him, a claim which the victim denied. When detectives later interviewed the officer in question, he told them he had never spoken with Brown's acquaintance; however, a Secret Service agent who was present at the scene later backed up the acquaintance's version of events. It's unclear why there are differing stories coming from law enforcement, but an internal review has apparently been initiated by the police department.

"We are aware of the discrepancy among witness statements in the Chris Brown case," wrote Police Chief Cathy Lanier in a statement to the AP. "This is not uncommon in cases with multiple witnesses involved. We have received no complaint of misconduct on the part of any officer in this matter."

Brown—who was on probation at the time of the incident stemming from his assault of Rihanna in 2009—has denied all charges. He's due back in court on February 20.
