A former West Norfolk police officer has been sentenced to 16 months in prison after selling 10 rare medieval gold coins.

David Cockle, 50, who was based at Downham Market station, found the Merovingian Tremissis coins while metal detecting between 2012 and 2015.

He did not declare the find to a coroner or the landowner where the coins were found, and sold them on for £15,000.

At Ipswich Crown Court on Wednesday, Cockle, pleaded guilty to one count of theft relating to the 10 coins on January 25 and was also given a five year Criminal Behaviour Order.
