6 inmates injured in Corcoran prison brawl

FRESNO, Calif. (KFSN) -- Six inmates were injured, including one in critical condition, after a large fight at the state prison in Corcoran.

Authorities say one inmate was attacked by two others in a maximum security dayroom on Thursday night. That quickly turned into a brawl involving 20 inmates.

Guards shot one of them, and used foam bullets and pepper-spray grenades on others to break up the fight.

The investigation is still ongoing.
