HARTFORD - A Hartford teenager is facing criminal charges today for allegedly sucker-punching an elderly man on camera.

Police released the video yesterday. They say it's a game called the "knockout game" where kids try to knock someone out with one punch.

In this case, the victim was not seriously hurt.

Police say they were able to identify the teen from the video that was being passed around Hartford High School.

He allegedly admitted to the attack, but claimed he thought the man was going to fight his friend.
