A Ladbrokes cashier was left "scared for her life" after this gunman pointed a shotgun at her in Burnham.
Police are investigating an armed robbery at Ladbrokes in Station Road, at Burnham on Crouch.
A man had entered the store shortly before 8.25pm on Sunday December 14 and had threatened a member of staff with what is believed to have been a shotgun.
Detective Dan Smith said: "This was a traumatic experience for the member of staff; she could not have expected to have been faced by a masked man, pointing what appeared to be a shotgun directly at her demanding money.
"This violent incident has left the victim scared for her life and it will no doubt have a life-long effect on her, all for the sake of £155.
"There are people within the community who will know who committed this crime and we urge them to come forward and speak with us.
"While you cannot see the man’s face in these stills I suspect there are people who will still recognise him from his clothing.
"They can call me with any information at Chelmsford CID on 101.”
