Video shows James Blake being manhandled by police officer

A surveillance video released by New York police showed former tennis star James Blake being slammed to the ground and handcuffed by an undercover officer. 

Blake appeared to have been caught by surprise as he was casually leaning against a beam outside his hotel, and did not resist arrest, according to the minute-long video released by the New York Police Department on Friday.

Blake, who is biracial, said he was detained for 15 minutes and that he suspected that a “racial factor” was involved in his brief detention. Police denied race was a factor, insisting it was a case of mistaken identity.

The city’s top police officer and mayor have already apologized to Blake, 35, for the incident.
