The 35-year-old African-American claims he was pushed to the ground and handcuffed by five officers outside a hotel on Wednesday (09Sep15) as he was on his way to the U.S. Open tennis championships.

A police spokesman tells TMZ.com Blake was "misidentified" as a suspect in an ongoing investigation into fraudulently purchased cell phones.

The insider says, "Once Blake was properly identified and found to have no connection to the investigation, he was released from police custody immediately. In regards to the alleged improper use of force, the Police Commissioner directed the internal affairs bureau to investigate."

Angry Blake tells the New York Daily News he can't be sure his race was a factor, but he's upset about the unjustified use of force.

He says, "To me it's as simple as unnecessary police force, no matter what my race is. In my mind there's probably a race factor involved, but no matter what there's no reason for anybody to do that to anybody."
