Shotgun robbery captured on CCTV

The pair escaped on foot with about £200 in cash

Police have released CCTV footage of teenagers who held up a petrol station in the Forest of Dean with a shotgun.

One teenager threatened a female shop assistant at Brierley Service Station with the long-barrelled shotgun.

The second teenager was carrying a knife. He vaulted over the counter to steal £200 in the raid, which took place on 25 August.

The pair escaped on foot despite a police search involving tracking dogs and the force helicopter.

A Gloucestershire Police spokeswoman said the two female shop assistants, aged 61 and 63, were not hurt but were shaken by the ordeal.

"They were very shocked and distressed by the raid. The shop was closing at the time and the attack was completely unexpected," she said.

"It's a very unusual incident for the Forest of Dean and obviously very upsetting for the people involved."

One of the teenagers is described as dark-skinned and was wearing a hooded top with the hood pulled up.

The second offender was taller and of slim build.

Ms Young said the CCTV footage showed cars passing the petrol station at the time the robbers left.
