CCTV images of a man detectives are trying to trace in connection with a jewellery robbery have been released.

The theft, at the Rox jewellers in Glasgow's Argyll Arcade, happened last month, when a man made off with a watch and ring worth more than £10,000.

He was chased by a security guard on to Buchanan Street at around 5.35pm on Friday September 27, but the worker lost sight of him in the King Street car park area near St Enoch Shopping Centre.

Detectives are keen to speak to anyone who recognises the man in the images, wearing a blue shirt with a white collar and pink tie. In the images released by police, he is seen walking past rails of clothes in a shop. Police have asked anyone with information to contact officers on the non-emergency number 101 or via Crimestoppers on 0800 555 111. The Rox brand was launched with a store in the Argyll Arcade in 2002 and opened its first branch south of the Border this year.
