CHICAGO (STMW) – A security guard contracted by the CTA handcuffed and sexually abused a teenage boy who jumped a turnstile on the Orange Line over the weekend, Cook County prosecutors said Thursday.

Christopher Buchanan stopped the 17-year-old when the boy tried to sneak onto the train after his card wouldn’t register at the L station at 4900 S. Kedzie early Saturday, Assistant State’s Attorney Tom McGuire said.

The teen explained that his card wasn’t working and Buchanan, 22, said he could head back to his workplace to get some money.

But as the boy started walking away, Buchanan asked him to come back with him to the CTA station, McGuire said.

Buchanan, who is studying criminal justice at DeVry, then directed the teenager into a restroom on the CTA property, McGuire said. There, he allegedly searched the boy before handcuffing him and ordering him to lie on his stomach.

Buchanan then removed the boy’s shoes and socks and rubbed his genitals against the boy’s foot, McGuire said. He then let the teenager go.

Buchanan, of the 4800 block of South Calumet, is facing charges of criminal sexual abuse and unlawful restraint.

When officers came to Buchanan’s house on Wednesday, he wasn’t there. But when his mom called him, Buchanan agreed to meet the police at 3900 S. Cottage Grove where he was arrested, according to a police report.

Judge Donald Panarese Jr. ordered Buchanan held in lieu of $25,000 bail.

Buchanan was working for Securitas Security Services USA at the time of the incident, CTA spokeswoman Wanda Taylor said.

CTA has a contract with the private security firm and asked that the company remove Buchanan from the contract Taylor said.
