The previously-unseen footage was filmed 11 years ago at secondary school in north London, where Mohammad Emwazi was educated.

In the film, obtained by Channel 4 News, the 'football mad' teenager, thought to be around 15 at the time, is the second person to be chosen for the team.

In This footage he also appears to be painfully shy, instantly raising his arm to cover his face when he knew the camera was focusing on him.

Channel 4 News said Emwazi had been identified in the video by two different people that he knew at the time.
A decade later, Emwazi had shunned British life and was a 'known wolf' to MI5, having already taken the path towards becoming ISIS' most notorious murderer.

He had moved to Britain in 1993, settling in the north-west London suburbs of Maida Vale and Queens Park.

He was also described as 'calm and decent' and 'the best employee we ever had' by an IT firm for whom he worked in Kuwait.

But, at some point during his lifetime, Emwazi was radicalised and was soon on the radar of MI5.

It emerged today that the Home Office could face fresh questions over border controls after it is thought that Emwazi used a well-worn route to leave the UK.

He had been watched by the services since May 2009, when it is thought he tried to reach Somalia to join Islamist terror group al-Shabaab. 

Emwazi flew to Tanzania with friends apparently on a safari - but was arrested by police upon landing in Dar es Salaam and sent back to Britain.
