MANILA - A riot erupted in the national penitentiary Monday, a month after 9 prisoners were killed in a brawl, the Bureau of Corrections said.
Investigation is ongoing.
Last month, 7 inmates were also wounded in a riot between "Sputnik" and "Commando" gangs at the east quadrant of the New Bilibid Prison's maximum security compound.
More details to follow.
