Two men approached the elderly resident on Westgate, Cleckheaton, and told him his roof needed work to repair
The victim agreed to have the work completed for a substantial sum of money and went to his bank to withdraw it.
He paid the workmen who told him they had completed the work while he was at the bank.
They both left in a van after being paid.
