L.I. perv had ‘dad’ set up kid sex: FBI

A former Long Island music teaching assistant was arrested after he was caught in an FBI sting that lured him with the sick promise of sex with a 13year-old boy — a horrifying hook-up the suspect thought was arranged by the child’s dad, authorities said.

Charles Bull, 53, of Sea Cliff, was busted Wednesday night and charged with an attempted criminal sex act and for endangering the welfare of a child. At an arraignment in federal court in Central Islip on Thursday, he was held without bail, a spokesman said.

According to a criminal complaint, Bull allegedly reviewed and signed a lurid confession. “I’m not going to lie, I was there to have sex with the 13-year-old boy,” the confession allegedly acknowledged, the complaint stated. “I know it was wrong, I can’t hide that and I know theres (sic) consequences. I had the condoms and Xbox card with me, the condoms for sex with him if it got past oral sex and the gift card as a gift for the boy.”

The court record showed Bull, currently unemployed, worked as a music teaching assistant at Locus Valley School District last year, and also worked at the School of Rock music school, which has outlets in Brooklyn, Manhattan and in Hoboken N.J.

According to feds, Bull, in an online chat room known as “LongislandDLMenOnly” — using the account name “Charlie Blue” — responded to a creepy post in which a father, who was actually an undercover officer, wrote he was on vacation with his son on Long Island looking for things to do.

“The Charlie Blue account then sent a private message to the ‘father’ asking for more information, which initiated a further conversation over private messages,” the complaint stated. “The Charlie Blue account asked about the sexual orientation of the father and the son and the son’s age,” which the fake dad told him was 13, the complaint stated.

“The Charlie Blue account expressed interest in pursuing sexual activities with the son and made arrangements to meet the father at a coffee shop in Farmingdale, N.Y.,” the complaint said.
