The torpedo head was destroyed at sea
Bomb disposal experts have blown up a torpedo head which was trawled up in the nets of a fishing boat off the Devon coast.

The device was brought up by the Katherine M on Sunday about one mile south of Plymouth breakwater.

Three Royal Navy divers carried out a examination of it on Sunday evening.

A temporary exclusion was put in place while the torpedo head was detonated by Explosive Ordnance Disposal (EOD) on Monday morning.

The Katherine M had been fishing off of Cawsands Bay, Cornwall, on Sunday afternoon when the torpedo was discovered on lifting her nets.

It was about 4ft (1.2m) long and about 1.75ft (0.5m) in diameter.

The torpedo was thought to have dated back to about 1920
After the bomb disposal team arrived at the vessel and examined the warhead on Sunday evening, it was then carefully hoisted off the deck and lowered to the seabed where it remained overnight.

The same diving team sailed out to the warhead again on Monday and used two 4lb (1.8kg) charges to detonate it at about 0930 GMT.

The Royal Navy said: "When the torpedo was detonated in a controlled explosion, it was accompanied by a huge plume of water, indicating the torpedo was live and had been a potential danger to shipping."

The warhead was not properly identified, but was thought to have been an early German submarine torpedo dating back to about 1920.
