There have been several recent incidents in the Sleaford area of Lincolnshire where a man has been cold-calling elderly residents offering to sell and fit door/window alarms. These alarms are believed to be of poor quality and are costly in price. The man concerned is described as being in his 50’s, thin build and balding with short grey hair. He was wearing a blue coat and riding a white mountain bike. He was also carrying a large holdall over his shoulder. PLEASE TAKE CARE WHEN DEALING WITH COLD CALLERS AND ONLY DEAL WITH REPUTABLE TRADERS.
