Caught on video: Vendor's teeth broken in attack from several teens on Dockweiler Beach

Three arrests have been made in a brutal attack on a Dockweiler Beach vendor that broke some of the man's teeth, but several people — some who may be teenagers — remain at large Tuesday.

The attack took place Sunday night on Dockweiler Beach. As many as seven people, who appeared to be in their late teens and early 20s, robbed the man, who had been working at a beach rental shop. 

Video from a bystander shows the young people punching the vendor, and trying to hit him with some kind of stick. One of the suspects was also believed to have a gun.

Three of the suspects were arrested, but were immediately released because they are under 18 years old, according to the LAPD.

Information about the other suspects was not available.
