RESIDENTS are being warned to be wary of crooks posing as police officers or tradespeople on their doorsteps in efforts to steal from them.

Greater Manchester Police say conmen or women may even pretend they are looking for a lost child or pet and ask to look in their homes.

But people must not allow this to happen to avoid a potential theft.

A force spokesman said: "Doorstep crime can affect anyone, but often elderly and vulnerable people are targeted.

"Doorstep criminals may also pose as police officers, a tradesperson, or say they're looking for a lost child/pet and ask to look in your house.

"These criminals often appear convincing and plausible."

To report an incident contact police on 101.

Fraud can be reported to Action Fraud on 0300 123 2040.
