Four Derbyshire teenagers have been cautioned by police after being caught in possession of cannabis.
Two 16-year-olds, a 15 and 17-year-old were caught in Eckington, Killamarsh and Dronfield as part of an operation to tackle anti-social behaviour.
Operation Rhubarb sees officers team up with members of the Community Safety Partnership to patrol "hot spot" areas on Friday and Saturday nights.
The teenagers attended police stations with their parents and were cautioned.
Officers also seized an off-road motorbike in Killamarsh during a patrol and issued a warning to a youth for nuisance riding.
