The head of a Chicago anti-violence organization has been arrested for allegedly hitting his wife inside their suburban home.

Tio Hardiman, the head of Cease Fire/Cure The Violence, was arrested for allegedly hitting his wife, Allison. According to reports, his wife only sustained minor injuries.

Hardiman’s organization works as a mediator between rival gangs to help reduce gun violence in Chicago neighborhoods.

In a 2012 interview with Time Out Chicago, Hardiman discussed what he thought was behind the increased violence in Chicago:

There’s a systemic issue where some African-American youth just don’t know how to deal with petty interpersonal conflict. Any slight issue turns deadly. People get into petty disputes, then they call their relatives who may be gang affiliated and it escalates into a gang-related type of incident. Revenge is in the air at all-time high levels, because people want to avenge the death of their comrades. So violence breaks out like an infectious disease. In some of these poverty-stricken neighborhoods, you’ve got a 52 percent unemployment rate, and an idle mind is the devil’s workshop. Guys in these crime-ridden communities go to sleep thinking about who they’re going to hurt the next day.

The group has received state funding since it was tapped to help quell the violence in Chicago.

Hardiman spent his early life in CHA’s Henry Horner homes and witnessed the devastation of violence first hand.

He is being held at the Hillside Police station.
