GARY, Ind. (AP) _ Authorities have removed three live grenades from a vacant trailer at a mobile home park in Gary.

Police Cmdr. Del Stout says officers were called Thursday morning after a manager at the Jordan Mobile Home Park discovered the items. The responding officers sought the help of the Porter County bomb squad to confirm the items were live grenades, and then evacuated people inside about 35 trailers in the park.

Stout says personnel from the Grissom Air Reserve Base in Peru took possession of the grenades and detonated them at another location.

Police say the grenades belonged to the trailer's previous tenant and were souvenirs from serving in Japan during World War II.

No one was injured and no property was damaged.
