Counter fraud work by the York Council saved taxpayers over £300,000 in York during the last year.
The figure is revealed in a report which will be considered by a Council committee next week.
The report reveals that it received 345 reports of possible fraudulent activity.
42% of the cases related to fraud in social care. 22% in Council tax/Rates, 18% related to housing fraud and 11 concerned benefit claims.
Officials also investigated the misuse of blue badges for parking. Officials claim that 84% of investigations were successful with two people prosecuted and a further 10 cautioned.
Three false applications for school placements were also halted.
In 2018/19 the team identified over £201,000 of losses to the council, for social care fraud. This was a 19% increase from the previous financial year. Over £137,000 of savings were produced which represents a substantial rise compared to 2017/18 (£38k).
Two people were prosecuted for fraudulently claiming monies, from the York Financial Assistance Scheme, that they did not require.
