The move comes five days after Lt Governor Najeeb Jung had directed the transport department to start a process of deregistering such polluting diesel vehicles in the city.
K K Dahiya, Special Commissioner (Transport) has written a letter to Delhi Traffic Police's Special Commissioner asking him to comply with the NGT order according to which these vehicles cannot be allowed to ply on the city's roads.
"The transport department has sent a CD of diesel vehicles which are older than 15 years to Delhi Police and asked the force to impound them immediately. These vehicles cannot ply and cannot be parked in public places as per the order of National Green Tribunal," sources said.
As per the green court order, city administration has to de-register diesel vehicles which are older than 10 years while directing the authority to phase out vehicles first which are older than 15 years.
Earlier this week, the Lt Governor had directed transport department to start process of de-registering these vehicles in the wake of city's pollution level reaching unprecedented level.
