The MP for Chippenham has spoken of how he chased a thief who snatched a bag from a woman in the Wiltshire town.
Liberal Democrat Duncan Hames said he had been sitting in his car at traffic lights on Friday when he saw the theft.
He pulled over, spoke to the woman to make sure she was unhurt and chased after the thief through Monkton Park.
He said a cyclist who also saw what happened managed to retrieve the bag. Mr Hames said he had reported the incident to Wiltshire Police.
"I pulled my car over as quickly as I could, spoke briefly to the lady to make sure she wasn't physically hurt, then ran into the back street's car park to see if I could catch the person who snatched the bag," Mr Hames said.
"If I hadn't been there I don't think it would have made any difference.
"A young man called Barry, who had the advantage of being on a bike, also saw the incident and he charged off into the park, managed to find the person who snatched the bag and was able to retrieve it for her."
