Officers are asking residents to be cautious when dealing with unsolicited sales calls after being contacted by residents that have been cold-called by a company selling therapeutic aids. The company is targeting older residents in the county, falsely claims to have received a referral from the local GP surgery and arranges an appointment to attend the home address.
The organisations which make these calls or supply these mailings often obtain householder information from commercial data companies which sell contact lists. Consumers can register with a number of preference services to assist householders to stop some direct marketing companies making such contact; these include:

Police are also offering the following safety advice:
Lock: secure all your other outer doors. The person at the door may intend to distract you while an accomplice gets in through a back door.
Stop: think about whether you're expecting anyone.
Chain: put the door chain on or look through the window or spy-hole to see who's there
Check: ask for an identity card and examine it carefully. You can always tell the caller to come back another time when someone will be with you.
Don't agree to sign a contract or hand over any money until you have talked to someone you trust.
Never disclose your personal identification number (PIN) or let anyone persuade you to hand over your bank card or go to the bank to withdraw cash for a payment.
Don't be afraid to ask a salesperson to leave. If they refuse, call the police.
