POLICE have expressed concern over reports of a man calling door-to-door in Billingham offering cheap central heating boilers.

Officers have received a spate of calls saying the man has taken money in return for cut-price heating offers and then disappeared.

The salesman tells householders he is from a local firm selling boilers for £600 to £800.

PC Richard Simms, of Billingham police, said: "If someone calls at your door offering services, check their ID, company details and any other information they may have. Ask for a phone number and phone the company to check if they have salesmen in the area that day. If in doubt, don't let them in."

Anyone with information should contact PC Simms on (01642) 302226.
