"A fight broke out inside the detention center that left 20 inmates wounded, four of them with gunshot wounds, and the rest were beaten and concussed. Two inmates died from gunshot wounds," Mejia said during a briefing.
According to Mejia, control of the prison was restored, but the Meshikles gang, which was involved in the clash inside the penitentiary, began rioting and attacking civilians in the city of Ciudad Juarez.
"As a result, nine people were killed in addition to the two deaths inside the penitentiary center. Among those killed by these criminals are four ... employees of Mega Radio, a host and three technicians," the politician added.
On Friday night, six members of the Meshikles gang involved in the attacks in the city were detained by police and soldiers. According the security ministry, the order in the city was restored.
