Wiltshire Police are investigating reports of fraud at the Old Railway Hotel, Porton.
It is believed that a bar employee has used their own card reader to take funds rather than use the business' account, up to a total of £2500.
A spokesperson for Wiltshire Police said, "We would like to hear from anyone who may have visited the hotel between December 4 and December 8, 2023, and has had a withdrawal to Take Over Enterprise Ltd."
"If you can help with our enquiries please contact us on 101 quoting reference number 54230130869."
