BOLTON police chiefs are urging homeowners to be on their guard against bogus officials.

As autumn approaches residents are being warned it is the time of year when the "bogus" type crime is at its peak, with many of those targeted being OAPs.

Now, as part of a crackdown on the bogus callers, people are being urged to check callers' details and ensure ID cards are handed over before allowing someone into their homes.

Chris Waters, crime reduction officer at Astley Bridge police station, said: "It does appear that the victim of these bogus types of crime are the more senior members of our community, although it must be stressed that all ages are at risk and, indeed, have become victims of the crime.

"Remember that you do not need to let anybody into your house who you are not happy with. Buy a chain for your front door and use it. Remember the adage: 'If in doubt keep them out'.

"If there is any uncertainty at all the caller should be asked to return later."

The advice comes just a few months after two men duped a 79-year-old woman at her Radcliffe home, stealing £300 after claiming they were offering garden work. Earlier this year a pilot scheme was launched in Little Hulton, Worsley, Walkden and Clifton to battle the bogus callers.

Police in the area teamed up with North West Water, social and health services and a clinical psychologist in a bid to beat the problem.

It came after statistics showed there had been 69 incidents since last October of conmen tricking their way into people's homes in the Swinton area. In nearly 40pc of cases the callers claimed to be working for North West Water.

Mr Waters stressed that the police should be contacted if anyone has suspicions.

He added: "Always remember to get a good description of any suspicious people to pass to the police and, if possible, obtain the registration number of their cars."
