Thieves stole £4,700 worth of tools from LJ Green Construction Ltd, in the fourth break-in for the company in four years.

Laurence Green, 42, the company owner, said: "I wouldn't like to guess whether the break-ins are linked, but the thieves were very methodical."

"It has an impact on our business because now we have to spend a lot of money getting new tools."

The police have CCTV of the incident, but if anyone has any further information please call 101.
