An unidentified man was recently caught on a store's surveillance video punching a pedestrian on a sidewalk in Cambridge, Mass. on Saturday afternoon.
Apparently, this assault was not part of the "knockout game," but the punch was just as brutal.
On the video (below), a man and woman are leaving a store when the cowardly assailant sneaks up from behind and blindsides the man in the head, notes CBS Boston.
The man fell to the ground, but suffered only minor injuries.
According to My Fox Boston, Cambridge police say at least three people were assaulted on Saturday.
In one instance, the assailant walked right towards a victim and punched him at least twice in the eye with a closed fist.
According to police, the suspect is a black man in his mid-20s wearing a black winter coat, dark hat and blue jeans.
