Police are asking residents in one area of Burnley to check if any items have been stolen from their cars.
The appeal came after police arrested a man at 5am today for vehicle interference near to Easdale Close in the Ightenhill area of Burnley.
He was found in possession of a bag containing £20 in loose change.
A police spokesman said: "We believe the money is from a number of cars parked in the area. We are appealing for nearby residents to check their cars and report any items, which may have been stolen overnight."
