The offender walked into the Shell garage in Whittlesey Road, Stanground, at about 10.25pm on Saturday brandishing a gun and a knife.

He demanded the member of staff hand over cash but he ran off to raise the alarm.

The offender tried to break into the tills but then fled empty-handed.

He is described as white, in his 30s, wearing a high-visibility sleeveless jacket over a dark blue hooded top, a face covering, grey gloves, grey tracksuit bottoms and red trainers.

Det Con Kevin Poole said: “This was a terrifying ordeal for the member of staff.

“While his face is not visible on the CCTV, the offender was wearing very distinctive clothing and I would appeal to anyone who saw him leave the store or recognises the description, to call police.”
