An old Korean-War vintage hand grenade was detonated by the area bomb squad Thursday after the explosive was discovered at Arbor Vitae.

"....in short order we had an officer from the Oneida County Sheriff's Office who is on the bomb squad secure the hand grenade and then a short while later an officer from the Marathon County Bomb Squad came and they recovered the grenade and took care of it at a local gravel pit...."
