ALLEGED DOG killer David Smith has been forced to boost security at his Seaham home after receiving death threats.

Since the allegations were made against the businessman, malicious phone calls have been made to his businesses and home.

Mr Smith’s wife Maureen and his daughter answered some of the sinister calls.

To protect his property and family, Mr Smith hurriedly installed CCTV, floodlights and other security measures after the allegations received national attention.

‘I am devastated by all of this,’ said the East Durham builder's merchant.

Durham police said they were not aware of any death threats, but confirmed the Smiths had received a number of malicious phone calls after the newspaper revelations that Smith had ‘executed’ up to 10,000 unwanted Greyhounds over a number of years and buried them on his own land.
