Stoke-on-Trent City Council's corporate fraud team uncovered more than 140 cases of fraud in 2023-24, saving residents about £3.6m.
Examples of fraud uncovered by the council include housing and council tax fraud, fraudulent Covid Business Grant claims and one case where social care worth £20,294 was wrongly claimed.
Housing tenancy fraud had accounted for most of the increase in fraud value, strategic manager Clare Potts told the council’s audit committee.
In total, the value of cases investigated by the council’s corporate fraud team in 2023-24 increased by £609,630 over the previous year.
