Photo of a young Jihadi John before he became the world's most wanted man

The boy with bad breath who became the world's most wanted man: Incredible footage emerges of Jihadi John at school as it is revealed he was a shy and insecure student who was bullied for having halitosis. Footage of ISIS executioner Jihadi John, real name Mohammed Emwazi, shows him as a teenager mingling with his classmates at Quintin Kynaston Academy, in Queen's Park, north London. The footage shows a teenage Emwazi sat among his classmates on computers during an apparent IT lesson as one student asks him: 'Mohammed, what subject are you revising today?' (centre).

Another clip shows him bounding around the playground while latching on to a big group of his peers, while another shows him with his arm covering his mouth due to his apparent fear of his bad breath (top right). The footage has emerged just hours after the 27-year-old was reportedly killed in a missile strike in the centre of Islamic State's stronghold of Raqqa in Syria.

 Emwazi, a university graduate from Queen's Park, London, was able to flee to Syria despite being on an MI5 watchlist and quickly became known as 'Jihadi John' for his appearance in a string of horrific killings (right)
