ORLANDO, Florida (AP) -- A federal drug agent shot himself in the leg during a gun safety presentation to children in what police describe as an accident. His bosses, however, are still investigating the incident.

The Drug Enforcement Administration agent, whose name was not released, was speaking April 9 to about 50 adults and students organized by the Orlando Minority Youth Golf Association, witnesses and police said.

He drew his .40-caliber duty weapon and removed the magazine, according to the police report. He then pulled back the slide and asked an audience member to look inside the gun and confirm it wasn't loaded.

Witnesses said when the agent released the slide, one shot fired into the top of his left thigh. The gun was pointed at the floor.

The agent was treated at Orlando Regional Medical Center and returned to work, a DEA official said.
