Chris Brown's Washington assault case has taken another turn in his defense. The District of Columbia police have opened an internal affairs investigation into statements provided by a police officer. The police officer's statement, given upon arriving at the scene, is being challenged by another official who heard a conversation between the police officer and one of Brown's aquaintances.

An unidentified acquaintance of Brown reports that the officer told him/her that the alleged victim said that Brown never hit him. The police officer was later interviewed by detectives and denie having any conversation with the acquaintance. However, "a uniformed Secret Service officer at the scene told detectives that he overheard the conversation with the officer and confirmed the acquaintance's story." The "victim" also claims that he never told anyone that Brown struck him, the documents state.

Seems like this case just got really difficult with the "he said/she didn't say" drama. Police Chief Cathy Lanier stated in a written statement, "We are aware of the discrepancy among witness statements in the Chris Brown case. 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."

"Nobody has accused anybody of lying. One person says one thing, one person says something else. Nobody has made an allegation that an officer is lying," added Lanier. Neither Danny Onorato, Brown's lawyer or the U.S. Attoney's office have commented on the matter. Chris Brown and his bodyguard Christopher Hollosy are both being charged with assault after allegedly punching a man who jumped into Chris photo with a fan.

Hollosy and Brown have both denied the plea deal that came with admitting to be guilty of the charges. There has also been talk about a surveillance video showing the events of that day. The alleged assault happened while the "Fine China" singer was still on probation in California for the 2009 attack on ex-girlfriend and singer Rihanna. The case is due back in court on Feb. 20.
