The Oregon State Police Explosive Unit confirmed Thursday that hand grenades found near a Grants Pass McDonald’s were live explosives.
The Grants Pass Department of Public Safety received a report Tuesday of a possible explosive device near the driveway of the fast food restaurant.
The Oregon State Police investigated further, finding a total of four hand grenades, three of which experts determined to be live.
“At the time of the recovery, the immediate area around where the devices had been located was checked and no other items of concern were located,” the Department of Public Safety said in a news release.
The agencies are in the process of checking the entire area for any other grenades but say there's no indication of any other devices or threats.
The Department of Public Safety is urging people to use caution if they see devices that may be explosive. It said people should contact law enforcement concerning any suspicious devices or packages.
