South Yorkshire Police have released CCTV images of a woman believed to have walked out of an off-licence with a safe under her skirt.
The woman is one of a group of four women and two men who entered the store on Bentley Road, Doncaster, on 10 May.
She went into the shop wearing trousers and left wearing a long skirt and struggling to walk. Police believe the safe was between her legs.
Officers have asked for information on any member of the group.
The woman went into a private backroom area while the other members of the group distracted store assistants.
Cash and jewellery estimated to be worth £20,000 were inside in the safe.
