Police have voiced concern about self-styled "paedophile hunters" who set up undercover sting operations amid fears they are interfering in their work and potentially entrapping innocent people.

Kent Police said it has "significant concerns about people taking the law into their own hands" and the methods used following recent stings by vigilante groups.

The latest incident happened at Bluewater Shopping Centre near Dartford on Easter Sunday when a brawl erupted after a group called "The Hunted One" confronted a man suspected of grooming a teenage girl.
