NYPD Detective Wojciech Braszczok has been sentenced to two years in prison for his role in the 2013 attack on a motorist and his family by a gang of bikers.

Braszczok, 34, was found guilty of assault and riot charges earlier this summer, and had been facing up to seven years in prison. He was acquitted of the most serious charges, first degree assault and first degree gang assault, for which he would have faced up to 25 years in prison.

The detective, who had previously worked undercover posing as an Occupy Wall Street activist, was off-duty when a group of motorcyclists got into a road rage fight with SUV driver Alexian Lien. Video showed Braszczok smashing out the rear window of Lien's Range Rover, delivering a few roundhouse kicks to the vehicle as his fellow bikers dragged Lien out and beat him. During his trial, Braszczok said his actions were "a reaction. It's not an intentional one."

As for why he fled the scene and left Lien and his family to fend for themselves, he said at trial, "My core concern is for me. So I'm leaving."
