STAMFORD - A Stamford man was allegedly attacked by a group of teens after he asked them to stop throwing snowballs at him.

The incident happened Thursday at 60 Atlantic St. in downtown Stamford at around 3:30 p.m.

The man, who does not want to be identified, says a group wearing sweatshirts that said Stamford Academy threw snowballs at him. After asking them to stop, one teen allegedly threatened the man, and the man walked away.

The teens then forced the man down on the ground and started to beat him. A nearby store owner says he witnessed the attack and called 911.

Police say the man was left unconscious while one of their officers arrested the main attacker.

Investigators say they're not sure why the man was targeted.

The man suffered a broken nose, a broken eye socket and two broken sinus cavities.

News 12 contacted Stamford Academy and a school spokesperson says that if their students were involved, they are disappointed.

Authorities are asking anyone with information to call the Stamford police.
