Police are appealing for witnesses following a series of bogus caller incidents in Bonnyrigg on Sunday (September 27).
The incidents happened between 9:40 am and 10:30 am and involved a man calling at homes in Pendreich Grove attempting to gain money for a charity race he was running.
He had no official paperwork or identification and provided no leaflets or literature.
The suspect is described as being in his 20s, of slim or athletic build, 5ft 10in tall and with light-coloured hair. He was smartly dressed with a black shiny jacket and smart trousers. He was holding a hand-written A4 piece of paper and a pen.
Inspector Andy Toombs said: “This is an opportunistic thief who is targeting older people. He has claimed to be a relative of the neighbours and used charity fund-raising as his cover to defraud people of their money.
“This kind of heartless crime will not be tolerated and we are actively targeting these kind of bogus callers through Operation Monarda.
“In this case, the homeowners were confident and clued-up on this type of crime and the suspect only got away with a small amount of cash.
“We would urge everyone to be on their guard if someone turns up unexpectedly at the door, use a door chain and if in doubt, don’t answer the door at all.”
Those with information can contact Police Scotland on 101 or alternatively, the charity Crimestoppers on 0800 555 111.
