This is the moment a group of black youths in masks sprinted away from the scene of a fatal stabbing of a 17-year-old White boy.
Sixth form student Thomas Taylor, 17, was attacked as he walked through the centre of Bedford on Wednesday night.
A nearby shop worker who witnessed the aftermath of the attack said he saw Thomas Taylor lying on the floor unconscious, and heard a man shouting down the phone 'he is dying, he is dying'.
A business owner who did not want to be named said he hadn't slept since the horror knife attack unfolded nearby.
