Some people collect seashells by the seashore, or even lost jewelry if they've got a metal detector. In one Oregon city, however, locals are making a more surprising, and potentially dangerous, find. In an alert issued last week, police in the city of Newport are warning beachgoers to beware of grenades that have washed up on the shore, as three were found last Tuesday in the stretch between Agate Beach and Yaquina Bay State Park, reports the Guardian. The bomb squad for the Oregon State Police confiscated the trio that's already been spotted, but authorities fear others may pop up, and that they may still be capable of detonating.
In a photo included with the alert, the devices are shown to be white with a label that reads "Warning: Explosive" and features the number M116A1, along with the description "Simulator, Hand Grenade." "If you encounter such a device, please do not handle or attempt to move it," the police implore in their warning, advising anyone who stumbles across one to call the cops. USA Today notes that, as of Monday, no incidents tied to the grenades, which are typically used in soldier training exercises, have been reported. It's also not yet clear where they came from.
