Essex Police have issued CCTV footage of a teenager they urgently need to trace in connection with the murder of John Pordage in Chelmsford.

A £10,000 reward is being offered via the Crimestoppers charity for information relating to the whereabouts of Bradley Blundell.

Detectives are trying to trace Blundell, shown in the video, in connection with the death of Mr Pordage in August last year.

The 34-year-old was shot in the chest at the BP petrol station in Baddow Road, Chelmsford, on August 5.

He died in hospital a short while later.

Now police say they have received information to suggest 18-year-old Blundell, from Chelmsford, may have left the country.

A jury at Chelmsford Crown Court found a second teenager not guilty of murdering Mr Pordage.

The 16-year-old, who cannot be named because of his age, was cleared by a majority decision.

Anyone with information on Blundell should call 999.
