A knife in the head

X-Rays, CT Scans & MRIs:

In this undated Metropolitan Police handout, x-ray images show how a teenage boy cheated death when a five inch knife was plunged into his head. The 16-year-old and two other young men were injured when they tried to stop a friend being robbed at a bus stop. He was rushed to hospital with the kitchen knife still stuck in his forehead after the attack in Walworth, south London, last November
