Eleven-year-old Jack is rushed to A&E after being hit by a motorbike while walking to his first day at secondary school. Jack managed to push his friend out of the way, but he was thrown up in the air and banged his head, fracturing his skull. He was taken to a local hospital but his injuries are so severe that he's been transferred to St George's. A CT scan reveals that Jack has a bleed on his brain caused by the fracture, and doctors are also worried that he may have internal bleeding. He's taken to intensive care.
