Teens accused of 'knockout game'

A "knockout game" incident took place in Paterson, NJ in December.

A video shows a 17-year-old approaching a pedestrian at the corner of Rosa Parks Blvd and Van Houten Street. After a brief pause, the suspect knocks out the pedestrian.

The video was allegedly taken by a 16-year-old, who later posted it on Facebook. The 16-year-old surrendered to police Saturday and the lawyer for the 17-year-old suspect said his client will turn himself in.
