Isaac Hunt, a man known in the community as an anti-violence activist, was arrested early Saturday morning.
Officers booked Hunt for alleged unlawful possession of firearm by serious violent felon. According to Indiana Code, "serious violent felony" includes voluntary manslaughter, a crime Hunt served a prison sentence for in the 1990s.
He was released later Saturday night on $4,000 bond with the promise to appear in court.
On Wednesday, Hunt was charged with Domestic Battery, a class A misdemeanor, and Unlawful Possession of a Firearm by a Serious Violent Felon, a level 4 felony.
Hunt has a 1:15 p.m. hearing Wednesday afternoon before a Superior Court Magistrate.
After serving time for voluntary manslaughter, Hunt has been outspoken in the South Bend community about non-violence.
He now works for Good Will Services as a community resource advocate and speaks with the city's group violence initiative program.
Most recently, Hunt attended call-in meetings with the city of South Bend to dissuade gang members from violent life styles.
NewsCenter 16's Tricia Harte talked to Hunt at a recent anti-violence event. You can see that interview here.
