A controlled explosion was last night carried out on a military shell which was being used as doorstep for the past 30 years in Teignmouth.
It was the second similar incident in two days.
A police spokesperson said: "Police were called to an address in Teignmouth today after a family member was concerned about a antique military shell that had been used as a doorstop for 30 years.
"Police arrived and requested Explosive Ordnance Disposal (EOD) from Plymouth.
"The device was deemed to require destruction by EOD and it was therefore transported to The Ness Beach very slowly!
"The beach was cleared and secured by police and a controlled explosion was conducted at 19:28. EOD allowed police to trigger the explosion.
"The device was a MK2 British 12LB Shrapnel round believed to have been brought back from Malta.
"This is the second explosive device dealt with by Teignmouth Police and EOD teams in two days.
"If you see anything concerning please report it to the police so that I can be assessed.
