Around 1.15pm on Thursday 25 March a woman entered a store in Applecross.
After browsing the store for some time, a staff member approached her offering to start a dressing room to try on the items she was holding.
The woman gave them to the staff member, but when she got to the dressing room she gathered all the items and walked out of the store, failing to pay before she left.
She was last seen jumping into the passenger seat of a silver Nissan Navara.
Police have released a CCTV image of a woman who they believe may be able to assist them with their investigation.
The woman is described as: tan skin, medium build with long dark hair. She was wearing a white tank top, black tights and black sneakers. She also wore a black crossbody bag.
