Bedfordshire Police have to confront the issues thrown up by a surge in the number of crimes related to the sexual exploitation and grooming of children by paedophiles. A man is lured to what he believes is a meeting with a 13-year-old girl, but is caught in a sting operation by so-called 'paedophile hunters'. A few days later, the case takes a surprising twist when police are called to a roadside where a pensioner is found badly beaten and suffering a bleed on the brain.
