(CBS) NEW YORK - An NYPD undercover detective has been arrested in connection with the Sept. 29 attack on a family in an SUV by a group of motorcyclists, CBS News has learned.

The officer, who has not been identified, is expected to be charged with criminal mischief for allegedly banging on and breaking the rear window of the SUV.

The detective waited four days before coming forward to the NYPD and he allegedly made false statements about his involvement.

The detective was one of at least three officers who participated in the ride through New York City that made national headlines after it was caught on video and posted to YouTube, reports CBS New York.

So far, four people have been charged in the melee that seriously injured at least one biker and left the driver of the SUV, a 33-year-old father, beaten in the street..

Police say the incident was touched off when a biker slowed down and bumped Alexian Lien's Range Rover. Video captured at the scene shows Lien surrounded by dozens of helmeted riders before he takes off and strikes one. The bikers give chase and Lien is eventually stopped, pulled from the SUV and beaten.
