The grenade turned up at a house in Ban Phak Khaya Noi, a village in Bok Subdistrict of Non Khun District on July 10, according to a statement from the Sisaket Provincial Public Relations Office published by Bangkok radio station Sor Wor Por FM91.

The homeowner, Rungnapa Duangta, had returned from a hospital visit and was resting on his porch when he noticed a rusty round object nearby.

He picked it up, saw what looked like a grenade pin, and moved it outside before asking an elderly relative indoors where it had come from.

The family dog had been carrying the object around and playing with it since that morning, he was told. Everyone had assumed it was a bone or a scrap of plastic.
