Footage has emerged of the moment a bungling robber tried to smash his way out of a petrol station - after a quick-thinking worker locked him inside.
Screwdriver-wielding Russell Hadley forced BP garage staff at Farthing Corner services on the M2 to hand over £300.
But while he was filling a bag with cigarettes, garage attendant Jamie Marks nipped out of the front door and locked him in.
CCTV footage shows hapless Hadley attempting to kick the glass door when he realises it is locked.
When that doesn't work, he picks up a fire extinguisher and repeatedly slams it into the glass.
After several failed attempts, he eventually manages to make a hole big enough to crawl through - only to be set upon by other customers outside, who struck him with traffic cones and whacked him on the head with a pole.
Hadley, 32, of Palmerston Road, Chatham, has since been jailed for three years after admitting robbery and criminal damage.
Investigating officer Detective Constable Daniel Bister said: "Hadley tried his very best to escape the shop following this robbery but the quick thinking of the staff prevented him from doing this.
"Various people using the service station also helped to keep him at the scene before officers arrived. I hope his sentence and the actions of those involved act as a deterrent to anyone else who may be thinking of committing a similar crime."
