This is the moment a bag snatcher fled a shopping mall - before running straight into a shop window as he tried to make his escape.
The mystery thief in Perth, Australia, was caught on camera sprinting from a shop after making off with a shopper's purse.
But in his haste to flee the crime scene, he mistakes a closed glass door as being open and slams straight through the window.
The robber appears to temporarily knocked out after crashing through the pane of glass - but still somehow manages to make a getaway.
Bystanders at the Market Place Shopping Centre are seen on CCTV going to his aid completely unaware of the bag snatching.
A second man then appears from the car park and threatens the good samaritans to leave him alone, dragging the hapless thief away.
Both men eventually make off in a stolen green Lexus, which police say had been taken from a home in nearby Mirrabooka.
The criminals are described as dark-skinned, about 15 to 25 years of age, between 170cm to 180cm tall, slim build with dark coloured wavy hair.
