A man who filmed himself skiing down a London Underground escalator is being investigated by police.
The 60-second film, which has been viewed by more than 100,000 people on the internet, shows the man hurtling down the 100 metre (300ft) escalator at Angel station in North London at a speed of more than 30mph.
In the footage, shot from a camera in the man's helmet, passengers can be seen strolling past as he fixes his skis at the top of the escalator. He then launches himself down the stairs, arriving to applause at the bottom seven seconds later.
British Transport Police said that the "naive and reckless" skier was liable for prosecution.

John Spelman, who produced the Norwegian DVD, yesterday insisted that passers-by had not been put at risk because friends of the skier had waned away members of the public immediately before the sunt took place.
He named the man as a Norwegian freestyle skier called Arild.
