Eleven motorcyclists, including an undercover New York police detective, have been indicted in connection with the assault on a man who was driving a Range Rover with his wife and infant son on the Henry Hudson Parkway, the Manhattan district attorney’s office announced on Friday.

All but one of the defendants were charged with gang assault. The 14-count indictment unsealed on Thursday came after witnesses testified before a grand jury.

The assault, which took place on Sept. 29, was videotaped and viewed widely on the Internet. The top charge against 10 of the men is first-degree gang assault; nine of those defendants are also charged with first- and second-degree assault. All are charged with coercion and riot as well.

The police detective, Wojciech Braszczok, 32, would face up to 25 years in prison if he is convicted on the top counts. He is free on $150,000 bail and has been suspended without pay. He has pleaded not guilty, as all the other defendants did.
