Madness of 30mph Tube escalator skier

London Underground today condemned a thrill-seeker who filmed himself skiing down a Tube escalator at 30mph.

The 60-second clip shows the man rocket 300 feet down the escalator at Angel station - the longest on the Tube network.

Stunned passengers watch in amazement as the unidentified Norwegian skier straps on skis before launching himself freestyle down the stairs - with a camera attached to his helmet.

The footage, for an extreme skiing video called Mind The Gap, has become cult viewing on the internet, receiving more than 110,000 hits on YouTube in a few days.

Makers claim there was no danger as friends kept the upward escalator clear from below while the skier made his rapid descent.

A London Underground spokesman denounced the film as "dangerous and irresponsible". He said: "It could have resulted in serious injury or death, not only to the individual concerned but also other passengers. London Underground will press for the police to take the strongest possible action against anyone attempting a similar act on the Tube network."

The film's producer John Spelman of Skifilm said: "He said he did it between trains coming in to reduce the risk."
