Authorities say a grenade launcher, loaded with a live grenade, was left with other donated items at a Florida Goodwill store.
Employees at a Goodwill store near Tampa discovered the weapon on Sunday, the Bradenton Herald reported.
The Manatee County Sheriff's Office says the store manager told deputies that the grenade launcher had come in a shipment from another store several days earlier. Employees from the store where the launcher was originally donated said they sent it to another location, because they didn't know what it was.
Deputies say they disposed of the active grenade in a Hazmat locker, and the launcher was stored in the agency's property room.
