The twerp who led his mates round Broadcasting House on Friday Night is 19-year-old Faisal Shinwari from Wembley.
Two years ago, he nearly died jumping from Tower Bridge into the Thames, whilst being video'd by a friend for his YouTube channel, Carnage. He was knocked unconscious, and pulled from the water by an RNLI boat. His father, a mini-cab driver originally from Afghanistan said his son had promised never to put himself at risk again and was now going to concentrate on his A-Levels and train to be an engineer.
Here's Faisal launching his channel in 2014. Remember the face, in case he ever comes asking you for a job.
Here's another video that the police might like to take a look at.
