(AP) — An undercover detective who investigators said was off duty when he was recorded on video pounding on an SUV as a biker rally spiraled into violence was arrested late Tuesday.

Wojciech Braszczok surrendered to face riot and criminal mischief charges, New York Police Department spokesman John McCarthy said.

Braszczok was expected to make a court appearance Wednesday. There was no response to phone messages left with his attorney.

The attorney, Phil Karasyk, had said Monday that the detective, a 10-year veteran of the police force, had only witnessed other bikers attacking the vehicle. But investigators discovered video evidence showing him punching an already damaged back window, then twice kicking the side of the SUV before leaving the scene, according to two people familiar with the case. The people weren't authorized to discuss the inquiry and spoke to The Associated Press on the condition of anonymity.
