On Saturday, July 5, a woman entered Debenhams, selected a bottle of Hugo Boss fragrance and removed the security tag and packaging.
She then concealed the item and left the store making no attempt to pay for the item.
The CCTV image shows a woman who Avon & Somerset Police believes might have some information which can help their enquiries.
The woman is described as white in her early 20’s, 5’ 6 to 5’ 7 with a slim build and brown hair tied up in a bun.
She was wearing a light green/turquoise long sleeve top, pink trousers, brown sandals and carrying a red and white polka dot hand bag.
