ORLANDO, Fla. -- A Central Florida man successfully infiltrated a white supremacist group and fed domestic terrorism information to the FBI, a Local 6 investigation has learned.

In February 2006, Neo-Nazis marched on Orlando, fueling racial tensions and costing taxpayers hundreds of thousands of dollars in extra police costs.

Unknown to the Neo-Nazi group was that the manager of their event, David Gletty, was being paid by the FBI to gather intelligence.

Local 6 showed video of Gletty firing up a meeting in Central Florida and sharing a stage with a National Socialist Movement leader in Michigan.

Gletty said it was a role he did not relish.

"I was assigned (by the FBI) to the White Power Movement, Nazi, Skin-Head and Klan," Gletty said.

The FBI has confirmed it used Gletty extensively for years in other cases but infiltrating the Neo-Nazi group was different.

"They hate the Jewish race of people," Gletty said. "They hate black people. They hate Hispanic people. They even hate some of their own white people."

He said swastika burning was "not his cup of tea" but he was paid more than $20,000 cash for the work, the Local 6 report said.

"When you're given an assignment, you can't pick and choose assignments," Gletty said. "You take whatever assignment they give you. You smile and say, 'Thank you.'"

Gletty said he learned in late 2005 of a plan involving Orlando.

The National leader wanted a Neo-Nazi march in Central Florida, specifically in Tampa or Orlando, Local 6's Tony Pipitone reported.

"At the time, I was like, 'Oh, wow, this is crazy,'" Gletty said.

"So, it wasn't you idea?" Pipitone asked.

"No, it was not," Gletty said.

"And, it was not the FBI?" Pipitone said.

"No, it was not," Gletty said.

But having the march in Orlando was Gletty's doing so his FBI handler would have greater control, Pipitone reported.

"They decided if we can't stop it, we might as well be in total control of it through myself," Gletty said.

An Orlando parade permit showed the on-scene event manager was Gletty.

Gletty and several dozen Neo-Nazis drew out hundreds of counter-protesters during the February march.

Gletty's work for the FBI would emerge in federal court a year later after he helped the FBI arrest two former associates for using firearms to rob drug dealers.

Now, Gletty is training to be a private investigator with a firm headed by private investigator Sam McCloud.

However, he said he can't leave his past behind him.

"There are people who hate me," Gletty said. "There's people that want to have me hurt and there's people that would like to see me dead. But, I have not the time to worry about that."

"But you got to be looking over your shoulder?" Pipitone asked.

"Every day," Gletty said.

Local 6 confirmed Gletty's dealings with the FBI by court documents, contacting former white supremacist associates and reading news and police accounts from Jacksonville to Alabama.

The FBI said it did not initiate, organize or sponsor the Orlando Neo-Nazi March.
