Vehicles seized by police as part of an operation to tackle drugs and crime could face the crusher.
Over 130 were seized as part of Operation Sabredale which ran for two weeks in Bradford.
Now, those which have not been claimed could be headed for the scrap heap.
Bradford District Chief Inspector Dan Greenwood said: “One vehicle can potentially be used by a number of different individuals to commit crime within the district.
“Drugs and firearms offences, for instance, are often connected with the use of such vehicles.
“As they are unregistered, untaxed or uninsured, it can also be difficult to trace an owner.
“They are not only used as a tool in the commission of serious crime, but also present a significant risk to other road users.
“Alongside partners from the DVLA and VOSA, we seized dozens of illegally driven vehicles during the two weeks of Operation Sabredale. Those that remain unclaimed could potentially be crushed.
“We are working at every level to tackle drugs and guns and this is a key element in our continued efforts.
“If anyone has information about vehicles used in their community as ‘pool’ cars among criminals, I would ask that they get in touch on the non emergency number 101.
“Help us identify those who are using them and give us the location or details of the vehicle. Remember you call anonymously and in absolute confidence via Crimestoppers on 0800 555111.”
West Yorkshire Police and Crime Commissioner, Mark Burns-Williamson, said:
“I welcome operations such as this because they help to disrupt criminal activity that has a wide impact on communities.”
