A North Lincolnshire Council spokeswoman said: “The council works hard with the Department for Work and Pensions to combat fraud and has successfully prosecuted more than 20 people for fraudulently claiming benefits they are not entitled to.
“It is easy to report fraud. You can report it online at www.northlincs.gov.uk/quickclick or call 01724 296666. All calls are treated in confidence and callers can remain anonymous.
“Please help us clamp down on fraud and let us know if you suspect anyone who may be falsely claiming council tax, housing or any other benefit. We’ll do the rest.”
