A man brought three grenades — one of which was live — to a San Antonio Police Department Northwest Side substation early Wednesday, officials said.

The department's bomb squad was called to the Prue Road substation, in the 5000 block of Prue Road, around 6:30 a.m. when a man brought the devices in his vehicle, Sgt. Michael Oliva said.

Michael Navarro, 49, left the grenades in a cardboard box in his vehicle, then told Oliva and others he brought them to the station to dispose of them.

“We looked at him like, ‘What?'” Oliva said. “Bringing grenades to the (station) is pretty unusual.”

Navarro found the grenades in his late grandfather's house when the elder man died about 10 years ago, Oliva said. The devices had been at Navarro's home ever since.

A San Antonio Police Department report states Navarro didn't think the devices were dangerous until a recent conversation with a co-worker.

Oliva said the bomb squad took the devices, including the live grenade that still had a pin in it. The other two devices were determined to be training grenades, he said.

The substation entrance was taped off and kept clear while the bomb squad investigated.

Oliva said the man was right to have notified police of the devices but officers would have preferred he left the devices at home and not transported them.
