Anti-violence group CeaseFire is dropping leader Tio Hardiman after his arrest on a domestic battery charge, reports the Chicago Sun-Times. Cure Violence, the parent organization of CeaseFire, affiliated with the University of Illinois at Chicago, announced on its website that it will not renew Hardiman's contract when it expires June 30. He was on administrative leave after he was arrested Friday at his home. He is accused of punching and kicking his 47-year-old wife, leaving her with bruises, a cut to her neck, and a swollen lip, prosecutors said. Authorities said Hardiman was convicted of misdemeanor domestic battery in 1999. Hardiman called his ouster “a miscalculated decision.” He said of Ceasefire, “I brought it back to life.” He created the group's violence interrupter initiative, using ex-offenders to mediate disputes in high-crime neighborhoods. The strategy received international attention after it was featured in the award-winning 2011 documentary “The Interrupters.”
