Residents are being advised to be cautious after reports of a possible bogus doorstep caller in Belper, who claimed to be collecting for charity.
The advice comes following a number of reports from residents on Spencer Street on Wednesday, July 2.
A woman was calling at homes to ask for sponsorship for a charity walk for Help the Heroes for her son.
She was described as white, around 5ft 7in, aged in her 30s and with brown hair which was tied back. She had been wearing a navy coloured top or jacket.
There have been reports of similar incidents in the Ripley area in January and in the Chesterfield area in November 2013. An investigation is currently on-going.
Community Safety Inspector Russell Dakin said: “I would urge residents to be cautious with anyone calling at homes unannounced and would encourage people never to hand over cash unless it is someone they know and can trust, or if they have identification which can be verified with the organisation they represent. If you notice anyone acting suspiciously in your area, or if you have any concerns about a doorstep caller, then report it to the police as soon as possible so that officers can make checks.”
Anyone with information should contact Derbyshire police on 101 or call Crimestoppers anonymously on 0800 555 111.
