Authorities say workers sorting through a catch of sea clams found more than 100 hand grenades in New Bedford, triggering an evacuation of the area and a response from U.S. Navy bomb experts.

The fishermen were looking for clams off the coast of Long Island and found the catch with the grenades in New York. They drove from Long Island to New Bedford with the grenades in tow - not realizing they had a potentially deadly situation on their hands.

New Bedford Police Lt. Steve Forand said on Friday that the explosives were found on Thursday. He did not have information on whether the grenades were live, how they ended up in the sea and for how long they had been submerged under water.

Police say experts from the U.S. Navy Explosive Ordnance Disposal Group had secured the scene and were in charge of the situation Friday.

Grenades can react or change when they come into contact with air - making it all the more lucky that the grenades made the trip from Long Island to New York without incident.
