Detectives investigating an armed robbery in Cheltenham on Tuesday morning are appealing for dashcam footage after the offenders fled the scene in a vehicle.

Shortly before 11.15am on Tuesday 20 November a group of masked men forced their way into a jewellers on Montpellier Walk with a sledge hammer (pictured below).

The three offenders took thousands of pounds worth of jewellery and left the scene in a blue Audi A3.

This car was soon found alight in nearby Lypiatt Drive and it's believed the offenders then got into a silver/grey vehicle which headed in the direction of the A40 Andover Road. It is unclear if it travelled towards the Oxford or Gloucester direction.

Tens of thousands of pounds worth of jewellery was soon recovered by officers from underneath the burnt out A3 and it's believed this was dropped by the offenders when they switched vehicles.

Detective Sergeant Jon Williams, who is leading the investigation, said: "I'm keen to hear from anyone who saw the offenders flee in the second silver/grey vehicle and who may have dashcam footage of it travelling on the A40 Andover Road between 11:15am and 11:25am.

"In the process of the offenders switching to this vehicle they've dropped some of the most expensive items which were stolen from the store as we've recovered jewellery including rings which is collectively worth around £100,000.

"Our investigation is ongoing and we are reviewing CCTV and taking part in house to house enquiries, but we would ask for anyone who was in either area on Tuesday at the relevant times to please contact us or Crimestoppers anonymously."

CCTV images of three men police want to speak to in connection with the incident have also been released below.

Anyone with information, CCTV footage or dashcam footage relating to these vehicles or incident is asked to call police on 101 and reference 122 of 20 November.
