Lawyer: NYPD officer at motorcycle rally didn't see biker get hit or attack on SUV driver

The Range Rover involved in the bikers attack is being moved from the police precinct for further police investigation Saturday, Oct. 5, 2013 in New York. Last weekend, dozens of bikers stopped the Range Rover SUV on a highway, attacked the vehicle, then chased the driver and pulled him from the car after he plowed over a motorcyclist while trying to escape, police said. The driver, Alexian Lien, needed stitches after being pummeled by the bikers. The motorcyclist who was crushed by the SUV, Edwin Mieses Jr., of Lawrence, Massachusetts, suffered a broken spine and two broken legs and may never walk again, his family said.

A lawyer with the New York City detectives' union says an undercover officer present at a motorcycle rally that turned bloody did not witness the attack on an SUV driver.

Attorney Phil Karasyk (KEHR'-uh-sehk) says the detective was off duty when he joined the Sept. 29 rally.

He rode up Manhattan's West Side Highway after the SUV struck a biker. He followed the other bikers because he thought there had been a hit-and-run.

Karasyk says the detective later saw motorcyclists attacking the SUV. But he did not see the driver, Alexian Lien (LEE'-ehn), pulled from the vehicle.

The detective did not come forward to disclose his presence at the scene for three days. Department officials are looking into the delay.
