SARASOTA, Fla. (CBS Tampa) – The Sarasota Police Department received an explosive surprise when a man brought a live grenade to their headquarters Thursday afternoon.

The man, whose name was not released, was not a terrorist – he allegedly found the device in a bag on his front yard, placed near his mailbox.

Lt. Randy Boyd told CBS Tampa that the man then drove to the department with the grenade in the passenger seat of his car.

“The front desk officer called me, so I stepped out and looked in the bag. It absolutely was a hand grenade, with what appeared to be a pin holding the handle down,” he recalled. “The bomb technicians … determined the grenade was live, and detonated it in a hole nearby.”

Though there are trained officials on hand to deal with incendiary devices, this is not an everyday occurrence.

“It was a very interesting day,” Boyd added.

Though the situation resolved itself without injury or extensive damage done, officials stressed that driving over a live grenade is not the proper way to handle the situation.

“When you find something that looks suspicious, call us – don’t move it,” Boyd said. “The next move you make could be the move that makes it [explode].”

The source of the explosive, as well as how it wound up in the hands of the man who brought it in, is still under investigation.
