GRAND RAPIDS, MI -- Federal authorities are confirming that a storage unit rented to former WCSG radio host John Balyo had a "bondage" kit that contained items including handcuffs, chains and duct tape.

Balyo is charged with first-degree criminal sexual conduct involving an 11-year-old boy. Police allege he paid a Battle Creek man to arrange for him to have sex with minors.

The "bondage" type items were discovered in a suitcase after a Friday, June 20, search of a Plainfield Township storage unit. Investigators also found a padlock, rubber gloves and children's socks, authorities said.

A Homeland Security Investigations source said Balyo gave police consent to search the unit after he was arrested at a Christian music festival in Gaylord.

Balyo was a morning show host at the Christian radio station. He was released on Saturday, June 21.

Investigators also found folders with magazines and articles about missing children, as well as children's obituaries, according to the homeland security source. The source confirmed that police found a publication, titled "Gauntlet," that talked about erotic photography.

Balyo is awaiting a July 7 probable cause hearing in Calhoun County District Court.
