NASHVILLE, Tenn. (AP) – The state is investigating an abuse complaint against a therapy group in Memphis that claims to turn gay teens into heterosexuals.

The Department of Child Services says it received a complaint about Love in Action, which runs an outpatient therapy program. The complaint was screened and enough substance was found to open an investigation, state officials said.

All other details are confidential and the state can’t specify the nature of the complaint or investigation, said K. Danielle Edwards, a DCS spokesperson.

Love in Action, which runs a program for children and teens called Refuge, said the investigation is without merit and was filed anonymously by someone with little knowledge of the program.

“The Internet accusations on holding kids without their permission … and the other crazy allegations are ridiculous,” said John Smid, the group’s executive director.

The group’s work has been the focus of protest by gay-advocacy groups, who say it is dangerous and irresponsible to engage in so-called “ex-gay therapy.”

Earlier this month, a blogger going by the name of Zach said his parents were sending him to a religious organization that would try to convert him to heterosexuality.

The teen identified himself as a 16 year old from Bartlett and said his parents “tell me that there is something psychologically wrong with me … I’m a big screw up to them, who isn’t on the path God wants me to be on. So I’m sitting here in tears … and I can’t help it.”

Edwards said DCS can’t say if its investigation is related to that boy’s situation, or even specify when the complaint was filed.

But Smid says it is connected. He said the accusation was likely filed by someone who just read the blog and used it “as a foundation to stir up a bunch of stuff.”

“The doors are not locked down and the kids are not required to be here, and they come here with their parents,” Smid said.

The Web site for Refuge says it offers programs ranging from two to six weeks. The group says it “is a ministry designed to be a safe place for young people and their families to find true freedom from addictions through the power of Jesus Christ.”
