Police are warning Wrexham residents to be on their guard against cold callers selling alarm systems.
It comes after residents across Flintshire reported that they have received calls from a security company providing various company names, selling security systems in recent weeks.
The callers state they are a government led organisation and that they are working for North Wales Police and for people to contact the control room to confirm it.
However, North Wales Police said that they have no association with the company and that there have been incidents where the cold callers have claimed that a serving police officer would attend the house to conduct a survey.
As well as false claims about working with the police the company claims that the alarm system is free or on a special offer, but have then been known to charge thousands of pounds for monitoring fees.
After a suspicious resident asked for a contact number, one was given which turned out to be the correct number for a security firm of the name provided. When contacted the company stated that they do not contact residents direct and do not arrange for police officers to attend.
If you receive such a call to your phone it is requested that you inform North Wales Police by dialling 101 quoting event reference number N117286.
Police advise that if you wish to purchase a new security system that you deal with local, reputable companies, or go via recommendations from family or friends
