Reports alleging that an undercover cop was not only witness to the West Side Highway biker gang assault, but may have actually taken part, were apparently true, as the cop in question was arrested Tuesday evening.
Detective Wojciech Braszczok, 32, was arrested and charged with riot and criminal mischief. He was a 10-year veteran on the force and was working undercover at the time of the assault.
The NYPD would not provide information on Braszczok's undercover assignment.
NYPD spokesman John McCarthy previously confirmed a detective had been placed on modified duty, turning in his gun and badge pending an investigation by the Internal Affairs Bureau.
But new video allegedly surfaced which showed a then-unnamed undercover detective punching and shattering the rear window of the SUV belonging to Alexian Lien, contrary to earlier claims that he had no part in the attack.

The detective had reportedly been criticized for not notifying his superiors he had been at the scene of the assault until days after the incident took place.
NBC New York reported that the video shows the detective smashing the rear window of the SUV, but riding off before the actual assault ensued. Sources reportedly told NBC the detective has not been truthful with his superiors.
In response to a query about the new video footage, McCarthy maintained that the investigation into the undercover detective is ongoing.
Braszczok is the sixth person to be arrested in connection with this assault.
