A group of murders have been caught on video chasing victims with knives just days before they killed a teenage 'like vultures' - but police still deny they have a problem with gangs.
Kyle Yule, 17, was stabbed to death outside his best friend's home in Kent.
But local police have insisted the murder - described by a judge as a 'revenge attack' - was not 'gang-related' or that there is a difficulty with gangs of youngsters rampaging with weapons in Medway towns.
Now footage has emerged showing the five youths convicted of murder chasing men with knives and belts.
A trial heard how Mr Yule was affiliated with 'G10' in Gillingham, while the defendants were part of 'C4' in Chatham and all had 'tags' or nicknames.
Both groups are described as gangs in a Medway Council report on tackling gang violence.
