NASHVILLE, Tenn. (AP) — Authorities say a Tennessee sheriff's deputy is on administrative leave after threatening to shoot his wife and her car mechanic.

News outlets report that Derrick L. Gleaves, a lieutenant at the Davidson County Jail, was arrested Friday for aggravated assault with a deadly weapon.

An affidavit says Gleaves confronted the mechanic, who was dropping off his wife's car where she worked, and accused him of having an affair with his wife. He then got a gun and threatened to shoot both his wife and the man, before leaving. The affidavit says Gleaves was still in full uniform.

No injuries were reported.

Gleaves told WSMV-TV in a statement that he wouldn't wish harm on the mechanic.

Gleaves was convicted of assault with bodily injury in 2001.
