Video 'shows undercover NYPD cop shattering rear window in savage attack on terrified SUV driver and his family'

Four bikers have now been taken into custody in connection with the brutal attack on Alexian Lien, his wife and two-year-old daughter last week

On Tuesday, Craig Wright was arraigned for allegedly stomping on Lien



NYPD cop initially said he did not intervene as he arrived too late

But sources say footage apparently shows him hitting the car's window



An off-duty undercover NYPD cop who denied any involvement as his fellow bikers ripped a father from his SUV and beat him has been seen on video smashing the rear window, it emerged today.

The footage apparently shows the unnamed officer, who is a veteran of seven years, banging on the window and shattering it before the driver was pulled from the vehicle.

The cop then rides away from the scene, sources told NBC . The video, which is being reviewed, is not the same as that which has been widely circulated following the September 29 attack.



Sources added to the New York Post that the cop initially told investigators he did not intervene because he arrived too late to stop the vicious beating.

The officer is assigned to the NYPD Intelligence Division, but sources did not reveal whether he was on assignment or whether his actions were a ploy to protect his cover.

Michael Palladino, president of the NYPD detectives' union, said the undercover officer was forced to make a difficult decision.

'Compromising his identity could compromise all the work he's doing and his safety as well,' Palladino told NBC. 'It's very difficult to lead a double life.'

The officer now faces an internal investigation because he didn't inform higher brass that he was with the bikers, let alone the crime scene, until three days after the attack, the Post said.

But police believe that they cannot press charges against the officer because another biker, Allen Edwards, 43, who punched the window of Alexian Lien's Range Rover before he was attacked in front of his wife and two-year-old daughter, had his charges dropped.

In court: One of the bikers, Craig Wright, was arraigned on Tuesday on charges of gang assault in the attack



Accused: Wright, with his attorney Mitchell Elman, allegedly stomped on Lien three times in the video Manhattan district attorney’s Trials Division, Karen Friedman Agnifilo said that the city cannot chase everyone involved saying: 'Prematurely charging individuals with low-level crimes does not further the goals of the investigation and could weaken the cases we expect to bring against the perpetrators of serious crimes.' The explosive development came as another biker headed to court over the incident. Craig Wright, 29, was arraigned in Manhattan Criminal Court on Tuesday and ordered held on $100,000 bail, even though his lawyer said he was innocent. Prosecutors argued that Wright, from Canarsie, Brooklyn, had been caught on video stomping of Lien at least three times after he was dragged from the SUV.

Wright was arrested Monday on charges of gang assault, assault and unlawful imprisonment.

Police say the bikers swarmed the SUV on a highway and when driver Alexian Lien bumped a motorcycle whose rider, Christopher Cruz, had apparently deliberately slowed down, several bikers surrounded the SUV and began to damage the vehicle.

Lien sped off, plowing into a motorcyclist. Bikers chased the SUV, pulled Lien from his vehicle and began beating him in front of his wife and two-year-old daughter, police said.

Large portions of the September 29 incident were captured on video and posted online.

Three other bikers, including Robert Sims, 35, and Reginald Chance, 37, both from Brooklyn, have been charged in the incident. Authorities say Sims is the man captured on video pulling open the door of Lien's SUV, and that Chance was seen using his helmet to bash in the vehicle's window.

Christopher Cruz, faces charges of unlawful imprisonment, reckless endangerment, reckless driving, endangering the welfare of a child and menacing.



Police say Cruz triggered the initial confrontation by slowing down his bike and then going to confront Lien after being bumped. Cruz has denied brake-checking Lien and says he was merely trying to exchange driver information.



Lien has not been charged. The biker he ran over, Edwin Meises Jr., suffered two broken legs and spinal injuries that his family says will leave him paralyzed.



Lien's wife has said her family was in danger and her husband had no choice but to flee the scene.

This comes as Cruz says it's his life that's ruined.



The 28-year-old father of two claims he never intended to box in Lien's Range Rover SUV on New York City's West Side Highway - he was only changing lanes and looked back to see where his friends are.



Cruz isn't charged with participating in the horrific six-on-one beating that left Mr Lien hospitalized, but police believe that he was trying to force him to slow down or stop. He is charged with reckless driving and false imprisonment.



He says the charges and the publicity from the case have ruined him.

'It's turned my life upside down right now,' he told ABC's 'Good Morning America' Monday.



He also denied that he was driving recklessly.

'I had no intentions to slow him down or to cause any type of problem,' Cruz said. 'I didn't think I was doing anything wrong by just cutting into another lane.'



Video from a fellow rider's helmet cam shows Cruz looking back as he changes lanes inches in front of the SUV. Lien then struck Cruz's motorcycle.



After the collision, Mr Lien then panicked and plowed through the crowd of bikers that stopped around him.



Mr Lien called 911 and attempted to flee the bikers, but they chased after him.

When he exited the highway and had to stop for traffic, several furious bikers attacked the SUV, pulled Mr Lien and brutally pummeled him - including stomping on his head.

But Cruz says he has no guilt about the incident, which all started with the crash he is accused of causing.



'I don't feel responsible,' he said. 'But I do feel bad for the family that go hurt.'

The New York Post reported this weekend that detectives believe up to six bikers participated in the savage beatdown of Mr Lien.
