A woman who had shopped in a local market in a town near Naples got quite a surprise when she opened the sack of potatoes that she’d purchased.

She took out the potatoes to wash and peel them and discovered that one of the potatoes was really a hand grenade that had apparently been left over from World War II.

Olga Mauriello had put the potatoes in a pot of water and had begun to peel them when she found the explosive which was heavily covered in dirt. Alarmed, she called her neighbors who in turn called the police.

The police ended up detonating the grenade the next day in a nearby park. The grenade was believed to have traveled with the potatoes from France.
