A LONDON COURT HAS CONVICTED a man for his role in a £40m jewellery raid on Graff Diamonds’ store in London in August 2009.

The BBC reports that Craic Calderwood, 28, of no fixed abode, is the fifth person convicted for the robbery.

The court heard that a Graff’s employee was held at gunpoint during the raid and was abducted to allow the thieves escape.

Calderwood was convicted at a re-trial after jurors at his original trial were unable to reach a verdict. Today he was sentenced to 16 years for conspiracy to rob and five years for possession of a firearm, the London Daily News reports.

The 43 expensive pieces of jewellery taken in the raid have yet to be found and a £1m reward is still on offer for their recovery.

Following Calderwood’s conviction and sentencing, the officer leading the Graff’s invesitgation said:

This latest conviction is a successful conclusion to this part of what remains an ongoing investigation. I’d like to thank all the victims and witnesses who supported us throughout this prosecution despite the fact that it has meant reliving this violent incident.
