A 13-foot German torpedo from World War II has washed up on a beach along the Baltic coast, police said.

The torpedo was found early Wednesday by a cleaning crew at Timmendorf Beach, Luebeck police spokesman Detleff Riedel said. Police secured the area and explosives experts were called.

Experts said it was a German torpedo made during World War II. Only the midsection fuel tank washed ashore. The explosive warhead was not attached.

The torpedo was taken away for further examination, Riedel said.

Bombs that failed to detonate during World War II are often found in fields and construction sites in Germany. Many tons of unused German munitions were also dumped in the Baltic Sea after the war ended.
