FIFTY people in Huntingdonshire were prosecuted for benefit fraud last year following more than 300 tip-offs from aggrieved members of the public. In total, Huntingdonshire District Council's investigators probed more than 350 allegations of fraud, two-thirds of which were found to be justified, involving a total of nearly £630,000. In all, there were more than 700 reports of possible Council Tax benefit and housing benefit fraud, with many other tip-offs coming from Government departments, including the Department for Work and Pensions with which HDC investigators work closely. Two out of every three investigations resulted in benefit being stopped or reduced. Fifty of the most serious cases resulted in criminal prosecutions with prison sentences of up to 12 months being imposed. A further 70 people received cautions or had to pay fines to the council on top of repaying the benefit they had claimed, HDC said yesterday.
