Police are urging shoppers to be vigilant after a man who claimed he needed directions distracted a woman while her purse was stolen.
Officers are appealing for witnesses following the theft, which happened at Asda in Rushden between 5pm and 6pm on Monday, February 4.
A 56-year-old woman was returning to her car which was parked in the underground car park at Asda.
A man approached her, asked for directions and opened a large map against the side of her car. On returning home, the woman realised that the interior light was on in her car and her purse, containing cash and bank cards, had been stolen.
The man is described as white, of slim build, 5ft 6in, in his mid 30s, with dark, thinning hair and wearing a light-coloured raincoat.
Detective Inspector Ali Farr said: “It is possible that there was a second offender, who reached into the car while the lady was giving directions. We would like to speak with anyone who witnessed this incident or anything suspicious in the Asda car park at the time.”
Anyone with information should call Northamptonshire Police on 101.
