This footage shows the moment an armed robber held a cashier at gunpoint while a group of masked men stormed the store.
In the video, a hooded man - dressed all in black - can be seen pacing towards the counter before pointing a gun directly at the cashier.
Another camera installed at the front of the store shows men raiding the store's shelves.
The gun is held centimetres from the cashier's face.
It happened in the Ocker Hill Store, in Tipton, in the Black Country on Thursday night.
The shop owner's daughter, Manjit Randhawa, has urged anyone with any information to come forward in a Facebook plea.
West Midlands Police confirmed they were called to the store after the armed robbery.
