Police are urging vigilance following two incidents in which members of the public discovered several boxes of Navy ammunition.

The boxes were washed up on two Roseland peninsula beaches over the weekend.

Inspector Rick Milburn said: “We are currently liaising with the Explosive Ordnance Disposal and Royal Navy in this matter.

"Over the weekend, we received two reports that ammunition was located on Porthbeor beach in Roseland and on Vault Beach in Gorran Haven.

“We informed the Explosive Ordnance Disposal (EOD) unit who handled the ammunition, which is believed to be highly dangerous.

“If located, we would ask the public not to approach these boxes but to contact police right away.

“Public safety is our priority and we have attached photographs of the boxes of ammunition. Anyone who sees anything similar washed up on a beach is asked to contact the police.”
