Law enforcement in Oregon have issued a warning to the public after at least three live hand grenades washed up on the shore of a beach along the state’s central coast.

Newport Police Department officers responded Oct. 4 to  the Newport area between Yaquina Bay State Park and Agate Beach after receiving multiple reports of “explosive” hand grenades being found, the department wrote in a news release.

The beach is about 110 miles southwest of Portland.

In all, officers have responded to reports involving three devices they said apparently washed ashore on beaches in that area.

The Oregon State Police Bomb Squad responded and seized the devices, the department wrote in the release.

As of Monday, no incidents had been reported in connection to the devices washing ashore.

The devices are white and have a label attached to them that reads “Warning Explosive,” police said.

A label on them reads it’s a Simulator Hand Grenade M116A.

It was not immediately known where the devices are from and how they ended up in the water and eventually on shore.

The police department could not immediately be reached for comment by USA TODAY.

“If you encounter such a device, please do not handle or attempt to move it,” the department wrote. 

Anyone who finds one is asked to call the local police department and report it.
