The Arizona Department of Public Safety bomb squad dismantled a WWII hand grenade Friday that highway maintenance workers found along U.S. 60, near Sossaman Road.
Lt. Steve Harrison, DPS spokesman, said there were no road closures after the 6:07 a.m. discovery because it was away from the road, over a hill and near a sound barrier.
Harrison said the grenade had been rigged into an improvised explosive device, or a home made bomb.
He said someone had filled the grenade with gunpowder and attached a detonator.
“It had the potential to explode. It may have just been a dud,” Harrison said.
The grenade was rusted and appeared to have been in the area a long time.
