After a group of teenagers viciously attacked another while recording it on video, police seek the public's help to identify the young men.

The video, posted to social media, shows two groups of teens near the Marina Bay in Quincy early Monday evening. Teens approached the group and directed graphic language at them.

Soon after, violence broke out. The teenagers kicked and punched the other group of friends.

The Quincy Police Department said officers are aware of the video and ask anyone who can help identify the involved parties call Massachusetts State Police, who are handling the matter, at 508-820-2300.
