Your average car thief or bail jumper has no idea as he drives along, but the van is packed with cutting-edge technology.
As soon as he drives past, the net closes in.
Cameras mounted on the back of the van clock the vehicle's number plate, sending the info into a computer containing nearly every national database.
An alarm sounds in the van and a specially-trained police operator instantly sees the vehicle and the driver's history.
Wanted for jumping bail on an assault charge? You're there, car nicked the previous day in Cardiff?, there's no escape.
The operator quickly radios a team of coppers a few hundred yards down the road, the car is stopped and another potential offender is off the streets."
