Children are being sent on a medieval knight's training course in one police force's latest attempt to stamp out anti-social behaviour.
Lincolnshire Police's Knight School has been introduced to instil an old- fashioned chivalrous code of conduct.
Teaching children the value of courtesy and respect before they become involved in anti-social behaviour is the aim.
The eight-week scheme has trained more than 100 children, aged between six and eight, in Spilsby.
Force officials claim the school is so successful that youth crime in Spilsby has halved since it was introduced.
A specialist in medieval history, Sgt Gary Brown started the course after noting that young people in his community began participating in anti-social behaviour at an early age, which led to criminality in their teens.
He designed the Knight School in an effort to combat this by teaching children old-fashioned values based on the knights' code of chivalry.
He takes groups of 12 youngsters who are recommended for the course by teachers who consider them to be on the brink of becoming unruly and disruptive in school.
Children who successfully complete the course, which involves everything from smartening their appearance to improving manners and taking part in community projects, are then knighted by the Lord Lieutenant of Lincolnshire, at a ceremony at Tattershall Castle.
As a reward, the trainees receive a set of armour, a wooden shield and sword.
