John Balyo had helped the traffic squad since 2004.
The group, which is a 501(c)(3), assisted with community parades and other events.
Balyo was arrested Friday in Gaylord at the Big Ticket Festival.
Monday, he was charged with two counts of criminal sexual conduct involving a child.
According to a police report, Balyo had sexual contact with a 12-year-old boy.
His former employer, Cornerstone University, fired him on Saturday from his position as morning show host with WCSG.
Balyo is expected to appear in court on June 30.
