An undercover New York police detective was caught on video pounding the Range Rover involved in a confrontation with motorcyclists a little more than a week ago, according to a law enforcement official. This is the same undercover officer who allegedly didn't step in to stop the attack on the driver because he was afraid of blowing his cover.
The video, which circulated the Web and is now in the hands of investigators, captured much of the incident. Five people were injured in the altercation, including the SUV driver. Three bikers face various charges, including first-degree assault, unlawful imprisonment and gang assault. It is not clear whether the undercover officer participated in the beating of the driver.
The altercation began on September 29 when Alexian Lien struck a motorcycle that had slowed in front of him on Manhattan's West Side Highway. The cyclist was slightly injured.
When Lien pulled to a stop, he was surrounded by bikers who hit his vehicle and spiked his tires, according to police. He pulled away, plowing into three more bikers, including one who was critically injured.
When Lien stopped again, his windows were smashed and he was pulled out of his vehicle and beaten, kicked and hit with motorcycle helmets, according to court documents. Lien was traveling with his wife and 2-year-old daughter, who were unharmed.
At least one other police officer is being questioned about witnessing or participating in the attack. Police have launched an internal investigation of him and the undercover officer. Both have been assigned desk jobs.
The lawyer representing the undercover detective has not returned multiple calls made by CNN. The NYPD and prosecutors are also not commenting on any police officers under arrest.
