He threatened the member of staff with a ‘rock hammer’, when they refused to hand over the money, he threatened a customer with the hammer. He then made off with several hundred pounds.

The common descriptions of the two are: Two males height between 5’ 6” and 6’.

The taller of the males is of slighter build wearing a light grey tracksuit top with a hood over his head and grey or darker coloured ‘jogging’ trousers or similar.

The shorter male had a larger/stockier build wearing light grey coloured hooded top again over his head and jogging style bottoms.

There was believed to be a large motif or writing on the front of one of the hooded tops.

Both males were wearing face masks, one of which was light grey in colour and one which was darker in colour.

Police are appealing for witnesses in relation to these incidents, particularly of the movements of the offender(s) both before and after the incidents.

We are also interested in potential vehicles that may have been sighted, or acting suspiciously in nearby areas.

DC Andy Houghton, from Gloucestershire Police’s CID, said: "These are serious offences committed by individuals who show no regard for the threatening behaviour and intimidation they have caused.

"We would urge people not to confront these individuals, as they are armed and would put you at risk of serious harm.

"However we ask that anyone with information to contact 101 quoting the respective incident number(s) or 999 in the event of an emergency."
