Police are asking the public to be vigilant after a number of reports have been made involving companies cold calling via the telephone, trying to sell alarms under the assertion that it is ‘Crime Prevention Week’ and that they work for South Yorkshire Police, both of which are false.

Although it is believed these companies are legit, there are a number who call residents and use high-pressure sales techniques and lies in order to force a sale.

Chris Squires Crime Reduction said: “If you are not entirely satisfied with the legitimacy of the caller, ask for their contact details and tell them you will call them back in an hour once you have had time to do some research. The Crime Reduction department of the police are always more than happy to advise on such a situation.”
