Over 1,250 police officers are taking part in a coordinated series of operations targeting those drivers who are more likely to be involved in criminal activity, who are five times more likely to be involved in collisions and less likely to have vehicles in a road worthy condition.
Since the Met Police Commissioner launched Operation Cubo in October 2011 as part of his commitment to target criminals and disrupt their activities, the total number of vehicles seized has risen to more than 44,000 - the most the Met has ever seized in one year.
More than 1,000 people have been arrested under Cubo for offences including rape, possession of illegal firearms, money laundering and drugs. Firearms, other weapons and large quantities of cash and drugs have also been recovered.
