Police are warning residents in South Yorkshire to be more vigilant as Christmas approaches - with reports of bogus officials trying to get into homes.
Four incidents are under investigation in Barnsley, where conmen gained entry into properties.
On Sunday an 85-year-old man allowed a man in a high-viz jacket into his home on West End Avenue, Royson, after he claimed he worked for the council and had come to inspect the heating and wall insulation.
Wallets and cash were discovered missing after his visit.
And last Thursday an 80-year-old man from Smithies Lane allowed a man into his home, who claimed to have brought some medication for the pensioner.
Cash was later found to have been taken from the house.
Incidents have also been reported on Ainsdale Court, Barnsley and Queen’s Drive, Gawber.
Detective Inspector Sharon Hancock said: “With Christmas just around the corner, burglars will be looking for any additional opportunity to enter properties with the prospect of stealing valuables and money.
“In these cases, the suspects have tricked unsuspecting and vulnerable members of our community in order to gain entry to their homes.
“I’d urge any resident that has concerns about bogus officials or rogue traders to call police so we can investigate. If in doubt, ask to see identification and don’t be afraid to close and lock your door while you make any necessary checks to verify their identity.”
Anyone with information should call police on 101 or Crimestoppers on 0800 555111.
