In the CCTV footage, shot in Liverpool, two men can be seen speeding alongside a payment on a bike.
Seconds later one of the helmeted thugs jumps off of the back of the bike and opens fire at the three lads.
The men scatter in fear, running for their lives, with some bundling into a shop for cover in the residential area along Hawthorne Road.
An innocent young woman narrowly escapes the carnage, walking into the shop moments before the strike at around 9.55pm last Wednesday.
A passing car can be also seen swerving around the waiting motorbike as the gunman fires the gun.
“We remain committed to tackling gun crime, stopping people who recklessly put the lives of others in danger and bringing them to justice”
Chief Inspector Matthew Moscrop
The bullets were fired straight into the mini-market, leaving a large hole in the glass front door, according to the Liverpool Echo.
The three young men emerge later from the shop completely unharmed and walk off down the road as if nothing had happened.
Amazingly the trio has chosen not to discuss the shooting with officers.
Merseyside police release CCTV stills last week and revealed the gunman fired two shots.
Temporary Chief Inspector Matthew Moscrop added that the passenger, who fired the shots, wore a distinctive black helmet with two prominent green stripes.
He said: “Did you see these two males leaving the scene after the incident at 10pm?
“We know they rode along Hawthorne Road in the direction of Kirkdale – did you see where they went after that?
“If you were driving in the area at the time, we would urge you to check dashcam footage that might show them.
“We remain committed to tackling gun crime, stopping people who recklessly put the lives of others in danger and bringing them to justice.”
