Thames Valley Police is releasing a CCTV image of a woman officers would like to speak to following a theft in Bletchley.
At around midday on Tuesday 24 November, the victim, a woman in her seventies, was shopping at Poundstretcher on Queensway when her purse was taken from her bag.
A large amount of cash was stolen, and her bank card was later used in an attempt to withdraw cash from an ATM but was declined.
Police believe the woman in this image may have vital information that could help with their investigation.
