The men convinced the 71-year-old she needed work carried out on her home in Whitburn, West Lothian, and visited the property a number of times between Thursday April 21 and Friday April 29.

On each occasion the woman either handed over money from the house or was driven to a bank by the men to get cash, police said.

A suspicious neighbour visited the woman to check the loft of the house and found that no work had been carried out.

All three men are white and travelled in a white van with ladders on the roof.

The first man is aged in his 30s, 5ft 10in with an average build, short brown/grey curly hair and a "scruffy appearance". He was wearing a dark fleece, blue jeans with a large belt buckle and black boots.

The second suspect is also in his 30s, around 5ft 6in with an average build, and short dark hair in a middle parting. He was wearing a black jacket, dark jeans and a hat.

The third man is in his 40s, around 5ft 5in with a slim build, short dark curly hair and glasses. He was wearing black trousers and a black jumper and may have Parkinson's disease, police said.

Officers are said to be following several lines of inquiry.

Detective Constable Debbie Trotter said: "After successfully conning the elderly victim out of a large sum of cash during their first visit, the suspects returned on further occasions and once again were able to secure more money.
