Robbers who broke into 20 shops with stolen cars were tracked by a police helicopter and caught hiding in a canal.
A police video shows the men reversing cars into multiple shop fronts in Birmingham, breaking the glass and dragging out safes and cash machines.
West Midlands Police said they stole eight cars to use as battering rams and inflicted £100,000 of damage on small businesses.
The men were caught last November when a police helicopter detected them forcing entry into a currency exchange in Kings Heath following reports of a break-in earlier that night in Dudley.
Frightened by the spinning blades overhead, the crooks fled empty-handed in the stolen Land Rover with a police chopper in pursuit.
They raced through residential streets then dumped the car and continued on foot.

Using thermal imaging, police in the helicopter directed officers on the ground to two of the men hiding in a canal and a third was caught by a force dog handler.
The fourth man was arrested weeks later.
All four were charged with conspiracy to commit burglary and on June, 24, and were jailed at Birmingham Crown Court having pleaded guilty.

Abdul Nasim, 20, and Saifullah Khan, 29, from West Bromwich, were both given five year six month terms.

Detective Inspector Tom Hadley from West Midlands Police Force CID, said: ‘This was an organised, determined and, on occasions, quite brazen conspiracy.
‘It caused substantial loss to small businesses.
‘The men caused extensive damage and misery to the business community, plus huge inconvenience to the eight people whose cars they stole to carry out the ram raids.
‘It’s estimated they caused damage in excess of £100,000 and carried bricks and pieces of concrete in their cars which they used as missiles to attack police and any members of the public who confronted them.
‘We suspect other men were also part of the conspiracy; our investigation continues and we are determined to bring all those responsible to justice.’
