CRESCENT CITY, Calif. (AP) — Officials at Pelican Bay State Prison have reported a second inmate riot in less than two weeks.

Officials say 50 to 75 prisoners began fighting around 7 a.m. Tuesday in the minimum support facility for non-violent offenders.

Prison spokesman Lt. Christopher Acosta told The Daily Triplicate that correctional officers were able to stop the brawl after five minutes without using force.

Acosta says four inmates were hurt, one of whom was taken to the hospital. He would not comment on the nature of the injuries, but said no weapons were found.

Tuesday’s incident follows a Nov. 13 riot involving 63 inmates in the maximum-security area. Three were injured in the brawl, which ended when officers fired a warning shot.

Acosta says the two fights do not appear to be connected.
