Undercover Cop Stood By While Biker Crowd Beat SUV DriverS

According to a report in the New York Post, one of the motorcyclists involved in last weekend’s violent road rage incident was an off-duty, undercover NYPD officer. Concerned about blowing his cover, the undercover officer reportedly stood by as Alexian Lien was dragged from his Range Rover and attacked.

The narcotics officer is a member of First Line Soldiers, a New Rochelle-based motorcycle group that also counts several other cops among its members, according to the Post's source. The officer reportedly came forward Wednesday night, four days after the incident and three days after a video of the chase went viral, and has hired an attorney.

“It is does not appear that he got involved at the scene,” one law enforcement source said of the undercover.

“He didn’t want to blow his cover” as an undercover involved in life-threatening duties, the source said.

The NYPD’s Internal Affairs unit is investigating whether other officers in the First Line Soldiers participated in or witnessed the attack. The NYPD has also identified the motorcyclist seen smashing the Range Rover's window with his helmet as Reginald Chance, 38, of Brooklyn. Chance has reportedly hired an attorney and is expected to turn himself in sometime Friday.
