Two Oklahoma prisons are on lockdown after an outbreak of gang violence involving makeshift knives and weapons that led to the stabbing of two inmates.
Prison spokesman Jerry Massie says the two inmates were stabbed Thursday after fights erupted simultaneously inside several housing units Thursday at Dick Connor Correctional Center in Hominy. Neither suffered life-threatening wounds, and both returned to the facility Friday.
Correctional officers used tear gas to break up the fights.
Another round of fights broke out Tuesday at the Mack Alford Correctional Center in Stringtown. Massie says several inmates were injured, but didn't require hospitalization.
Massie says both altercations are linked to an ongoing feud between Hispanic and Native American gangs inside the prisons.
