A bomb unit from Aberdeen Proving Ground was called to help dispose of a military ordnance found in a Carroll County home Monday night.
APG Spokeswoman Terri Kaltenbacher said Tuesday that the 20th Support Command went to a house in Westminster after getting a call about a military munition in the residence.
"Obviously someone had something on display or had collected something," she said.
The two members of the explosive ordnance disposal team were called at 6 p.m. to Manchester Road in Westminster, Maj. Carol McClelland said.
McClelland said an unexploded, 75-millimeter shrapnel shell was at the home, which is in a rural area and far from other houses.
"The on-scene commander decided the shell should be detonated," she said. "It was actually detonated on scene."
Kaltenbacher said the call was not a typical one for the command.
"They respond to events like this on an occasional basis. It's not regular," she said.
Kaltenbacher did not further information on the type of device or the exact address where it was found.
