Just outside Ripley, Derbyshire, officers head to a set of roadworks following a tip-off that a driver is suspected of regularly driving to and from his place of work under the influence of drink. When they arrive, they arrest a workman who is not only aggressive and appears to be drunk, but is wanted for being in breach of a court order, so is taken into custody. Police also tackle a surge in thefts from lorries, boxing in and intercepting a couple of known offenders with a history of burglary.
