A 71-year-old man has been arrested in connection with the theft of a historic gold trophy from Glasgow's Riverside Museum.

The artefact, worth almost £500,000, was stolen in October last year.

But Police Scotland did not publicise the robbery until April over fears the trophy would be destroyed.

The force confirmed the man was arrested on Thursday and later released without charge.

Officers said inquiries about the theft - which has been flagged to Interpol as a stolen artefact - were continuing.

The 18-carat gold cup was presented to Glaswegian merchant Sir Thomas Lipton in New York in December 1930, following his fifth and final attempt to win the Americas' Cup - the premier international prize in yacht racing.

It was donated to the city of Glasgow two years later, after Lipton's death.

The theft occurred overnight between 22 and 23 October last year, and there were no signs of the building having been broken into.

The missing cup - valued at £490,000 - was only noticed following cleaning on the morning of 23 October.

It is described as gold with two handles and a detachable domed lid, set on top of a silver square plinth base. It has an enamelled red, white and blue shield and gold ropework.

Police have urged anyone with information about the theft to come forward.
