Watch a video report by ITV News Anglia's Callum Fairhurst
The terrifying moment an armed robber holds an eight-inch knife to the throat of a shopkeeper - telling him 'we're not here for you, bruv, we're here the for the money' - has been captured on CCTV.
Two masked men burst into the store in Colchester, with one grabbing the owner in a headlock before the other rifled through the till.
Cameras captured the entire raid during which the robbers can be heard repeatedly telling the shopkeeper 'be quiet, bruv'.
As they order him to open the till, they go on: "Do not ****ing move, bruv.
"Do not press anything. What you pressing?
"We're not here for you, bruv. We're just here for the money, brother. Stay still, we're just here for the money."
As they hurriedly leave the shop they point at the owner, telling him "stay right there, bruv".
The pair, who were both armed with knives, fled the shop with about £500 of tobacco and £100 in cash.
The shopkeeper escaped with only a small cut in the robbery, which happened in Canterbury Road at about 7.15pm on Monday, 20 February.
Police were called but despite searching the area could not find the two men.
Officers have now issued descriptions of the two robbers.
The first man is white and was wearing a grey hooded top, grey tracksuit bottoms and dark trainers. He also had a dark puffer jacket on.
The second man is white and had a beard. He was wearing a dark jacket and navy jogging bottoms.
Police said they were examining CCTV images from the shop and nearby areas, and identifying forensic evidence.
They have asked for anyone with information, dash cam, mobile phone or CCTV footage of the area, as well as any witnesses, to contact them.
