An “armed” motorist drove off in a BWM after being Tasered during a police chase in a trendy area of east London.
Officers rushed Old Street, in Tower Hamlets, just before 6am on Monday to reports that two men in a car were carrying weapons.
They had also reportedly been involved in a fight, witnesses said.
As officers approached the vehicle the driver reached for something out of sight, prompting officers to set off a Taser, Scotland Yard confirmed.
Despite being Tasered the man sped off.
Just after 6am, police flagged down the car which had been involved in a crash with a Mercedes in Liverpool Road, Islington.
The driver and passenger ran from the scene.
Liverpool Road resident Ben Atfield said the entire street had been woken up by the “massive, crunching thud” of the crash.
He told the Standard: “A policeman told us the white car was fleeing Old Street after the two guys inside got into a fight with armed officers.
“They tasered him but he managed to escape.
“When he crashed the Taser cables were still hanging out of the side of the car.
“The black Mercedes had four women in who were driving by. Afterwards the two men ran towards Upper Street.
“Within three minutes armed coppers arrived here.
“A couple of the women seemed very shaken up. The neighbours took them in for a bit.”
A woman, who has been driving the other car, was treated for minor injuries.
No arrests have been made and enquiries continue.
