Almost 2,000 uninsured cars have been seized by Met Police officers.
On Thursday officers from across London’s 32 boroughs seized 554 cars in a day of co-ordinated operations.
Met Commissioner Bernard Hogan-Howe has promised a clamp-down on uninsured cars in the capital.
So far officers have confiscated 1900 vehicles in fours days of action.
MPS Commander Steve Watson, speaking after the latest operation, said: “We’re continuing to disrupt criminals by seizing their cars, meaning they’ll find it harder to operate.
“Yesterday’s operation was the latest coordinated day of action by the MPS. In addition to removing uninsured cars we arrested over 80 people for a range of crimes.
“We’ll be carrying on doing this throughout the year, disrupting criminal activity and taking more and more uninsured cars of the roads.”
The penalty for driving a vehicle without insurance is six penalty points and a £200 fine, and drivers also risk a driving ban. The Met says it seized 34,000 vehicles in 2010.
