Be alert - bogus builders in Carshalton and Wallington
Bogus builders tried to con two people - including an 87-year-old - out of thousands of pounds this week.
The would-be fraudsters tried to tell people their houses needed drying out because of nearby building work but neither of the intended victims fell for the ruse.
A supposed builder called at the house of an 87-year-old man in Beddington Gardens, Wallington, at 1pm on Tuesday. He said he was putting up scaffolding at a neighbouring house and needed the man's phone number because there was a problem and his boss would need to call him.
Later the man got a call from someone asking for £1,800 to prevent flooding and mildew - the man hung up on the caller and contacted police.
The person who called at the house was a white man in his mid-20s.
A 65-year-old man answered a call at his front door in Wrythe Lane Carshalton at 1.30pm the same day. He was told building work at a neighbour's house could make his walls damp and that he would need to pay a £2,400 deposit for a dehumidifier.
The man gave the caller his phone number and was phoned by a man purporting to be a Mr Collins who insisted on cash and said he would meet the man at a nearby location. The 65-year-old called police who waited at the location but Mr Collins failed to turn up.
The man at the door was white, 25 to 35-years-old, 5ft 8in, stocky and spoke with an Irish accent.
Police say people should shut their doors and call 999 if anyone calls on them trying out this scam.
