This week, officers are called out to an incident where a member of the public has been assaulted after he asked a man to stop vandalising a park. The victim is on the pavement bleeding when officers Dring and Williamson arrive. Several witnesses have stayed with the injured man and explain that they have even managed to get some footage of the alleged attacker on their phone. Control room cameras in the town centre also have the man in sight and can provide a good description to the officers on the ground. Other officers join in the chase to find the attacker and the man is eventually stopped by PC Smith from the dog unit and arrested.Elsewhere, the roads policing unit lead by PC Webb are looking for a driver who has failed to stop for officers. When they catch up with the car the driver has abandoned it and taken off on foot. Hoping to find out where he has gone, they call in PC Wong and his dog Senna to pick up a scent. After a promising start, Senna gets thwarted by the number of other people in the area; just as they are about to give up, details come through of a possible nearby address where he may have gone, and PC Webb pays him a visit. The suspect denies having driven that evening but after questioning the man further, the police arrest him.In the early hours of the morning in Cheltenham village, PC's Durrant and Bower have stopped a female driver for driving erratically. As they approach, information comes through that the car has been involved in the supply of drugs, which means it's much more than a traffic offence. After questioning the female driver, they decide to search both herself and the vehicle for drugs. They request a female officer to search the woman who has nothing on her, so they turn their attention to the car putting drug detection dog Marshall to work. Once again, the search comes back with no result leaving the woman free to go.PC Foxall and Special constable Webber spot a car that is driving very slowly. They run checks on the registration plate, and it is insured, but instinct is telling PC Foxall that something is wrong. As the officers approach the car to make further checks, the driver speeds off, but the car is being driven by a male when it is registered and insured to a female. With no pursuit capability, PC Foxall can't give chase and think they may be long gone but moments later, another unit reports in that the car is parked on a driveway in the area. At the house, a female answers the door and as they check inside, they find the man upstairs in bed pretending to be asleep. After arresting him for failure to stop, checks come through which reveal that he doesn't have a driving licence.
