Terrifying footage has emerged of pupils confronting a hooded knifeman who lunged at them as they walked home from school.
The video, which was uploaded to Instagram over the weekend but since removed, shows youngsters screaming with panic as the armed thug approaches them in Buckinghamshire.
One frantic boy is almost struck by a car as he evades the man.
The distressing incident appeared to be filmed by a friend of the knifeman, who was told not to do anything near the school.
Another hooded man is heard telling him: “There’s teachers gonna come, innit”.
When the man is seen brandishing a blade, one girl confronts him and says: “What you going do with the f***ing knife?”
