Shanks a lot, Rikers.
A surge in gang violence in the city jails turned July into the bloodiest month behind bars in at least 15 years.
Records obtained by the Daily News show there were 21 slashings and one stabbing in July. At least 16 of the incidents — leaving combatants with sliced faces, shanked backs and bloody ears — involved members of the Bloods, Crips or Latin Kings.
The violence erupted inside jail cells, showers and cafeterias. In one clash, eight gangbangers slashed an inmate about 11:30 a.m. on July 1 during a religious service in the main gym at the George R. Vierno Center, the internal records show.
“It’s pure savagery,” said Ed Gavin, a retired deputy warden.
