SAN FRANCISCO (KRON) — Investigators with the San Francisco Police Department are looking into a major brawl that happened at Justin Herman Plaza.

The fight happened in the afternoon of May 8, injuring a number of artists.

A vendor at the plaza sent this video to KRON 4. She says the fight started when two groups of skateboarders were fighting.

One of the artist vendor’s tried to break up the fight and then some skateboarders turned on him, destroying part of his display.

Still images show two of the artists, bruised and battered from the fight.

Police showed up soon after, but the artist who took the pictures said the skateboarders had already left.

No word on if any arrests were made.
