A bomb squad on Tuesday detonated a Japanese World War II mortar found inside the home of a deceased Lake County veteran, according to the Lake County Sheriff's Office.

The live mortar, along with other assorted ammunition, was found inside the Kelseyville residence by Public Administrator's Office employees while they were cleaning out the home, Lake County sheriff's officials said.

The Sheriff's Office evacuated the area and set up a 300-foot perimeter around the Pine Drive house in preparation for the explosion.

Using a remote controlled robot, an explosives team from Napa County inspected the mortar and prepared it for detonation. It was exploded without causing any damage to nearby structures, according to the Sheriff's Office.
