(CNN) -- Three people were shot, two fatally, at a Tallahassee, Florida, federal detention center Wednesday as federal agents went to arrest six corrections officers, authorities said.

The six guards were being arrested in an investigation into allegations that guards were trading drugs for sex with female inmates, federal law enforcement sources said.

One of those being arrested opened fire, said Jeff Westcott, spokesman for the FBI's Jacksonville bureau.

Federal agents returned fire, killing the suspect, Westcott said. An agent with the Department of Justice's Office of Inspector General died in the shootout, he said. (Watch what may have prompted the gunfight --

The victims' identities and details of the arrest warrants were not released.

The shooting occurred about 7:45 a.m. at a federal detention facility in Tallahassee. (See facility, map)

The Tallahassee facility holds mainly women, but includes an area holding men awaiting trial.

The facility was put on lockdown after the shooting, officials said.

-This took place at, oh, about three miles from where I'm working.

I'm not in the least bit shocked about the drugs for sex thing. I think everyone knows that is commonplace.

The fact that the guy shot at a federal officer coming to arrest him is the shocking part of this story.

The drug part, yeah, not too shocking, but the shooting and the proximity to well, me is rather shocking. It's something I see on the news once or twice a year. A shootout that takes place in another region and not in some quiant little college town. It's surreal, it's only a quick five minute drive away.

It must of been some killer sex to down a FBI agent.
