A brawl left three men stabbed at a Ventura County motorcycle festival Feb.11, police said in an Instagram post.

The incident took place about 1 p.m. at the annual Chopperfest at the county fairgrounds.

Two of the injured men were taken to Ventura County Medical Center and the third man went on his own, police said. The men were ages 33, 43, and 53.

No arrests have been reported.

Police said several attendees were fighting, and anyone with information is asked to call Detective Sgt. Pat Lindsay at 805-339-4498.

One response on Instagram said Chopperfest has been held for 20 years without an issue.

On its website, Chopperfest bills itself as “dedicated to the design, function and art of the motorcycle.” This year’s event was called the 20th Anniversary David Mann Chopperfest, named after a California artist renowned for his paintings of biker culture who died in 2004.
