And African-American tennis star James Blake has spoken out about being slammed to the ground by five undercover police officers as he stood outside his Manhattan hotel on Wednesday afternoon. Blake describes being tackled by a plainclothes police officer whom he initially thought was an old high school friend he didn’t recognize. He says he was cuffed on the ground for at least 15 minutes until one of the officers recognized him. The police say they had mistakenly identified Blake as a suspect in a case of credit card fraud. Following the arrest, one of the officers appears to have attempted to cover up the incident by failing to record the stop in the NYPD logs. NYPD Police Commissioner Bill Bratton said Thursday the arrest “should not have happened.”

Commissioner Bill Bratton: “We are very interested in speaking with Mr. Blake and hope to hear back from him to extend an apology for the experience he encountered. It should not have happened. … Concerns I have about what I witnessed on the video, as well as briefings I’ve received by Chief Reznick, the inappropriateness of the amount of force that was used during the arrest.”

At least one officer has been placed on administrative desk duty after the incident. Speaking on Good Morning America Thursday, Blake said he believes the police need to be held accountable.

James Blake: “When you police with reckless abandon, you need to be held accountable. And I think I’m hopefully going to let people know that some of them need to be held accountable. And these that are doing police work the wrong way need to pay for those actions and be shown either the door or whatever they need to do to punish them.”
