Police are searching for a person who left four hand grenades in a Westmoreland County Goodwill shop.

The grenades were found yesterday afternoon in a plastic box. The Allegheny County Bomb Squad rushed to the scene in Rostraver Township.

Police say the grenades were of a military surplus variety. They were removed from the store.

The store's assistant manager, Dawn Graham, says the grenades may have been in the store for days before they were discovered.
