A prankster's video of himself screaming Justin Bieber's name on the London Underground has gone viral.

He is also seen standing on the platform with a group of surprised school children around him at one point.
The comedian looks away oblivious to what's happened and carries on reading his paper as the public look on.
His loud screams shock many with others simply laughing at his actions.
