Britain's motorways are getting busier and with fewer officers on the road the motorway cops often need the public to tip them off about illegal cars and drivers. PCs Dale Anderson and Doug Lofthouse receive a radio report of an overturned car on the motorway and head off on foot to search for the missing driver. In Bradford, PCs Mike Wroe and Chris Spencer are on a night shift when they spot a car driving erratically. As soon as they take a closer look the driver puts his foot down and they give chase through the back streets and alleyways in the north of the city. The driver abandons the car near a park and as the cops investigate they are approached by the driver, who gives them a confession that takes them by surprise. PCs James Alderson and Paul Crabtree respond to an anonymous tip-off about a car that might be involved in drug dealing. After finding the car and following it, the cops box in the driver at the roadside and quickly apprehend the suspects. While some tip-offs come at a moment's notice, others require more planning and patience. Matt Hemingway and Aidy Brown are parked up just off the M62 bypass in Castleford on the lookout for a driver suspected of having a revoked licence. When they find him, he's surprised to discover that his car is being taken away, leaving him with no mode of transport for his daily commute. Back in Bradford, PC Bob Hoyle responds to a call of burglars making their way from the scene of the crime. When he stops the car full of lads and questions them they deny everything. But what they don't know is that they were caught on camera, proving that help from the public can make all the difference in the cops' fight against crime.
