Officials at London Underground have condemned the so-called ski-stunt of a Norwegian man who filmed himself skiing down a tube escalator and then posted the 57 second video on the YouTube Website. The video clip shows a man taking a pair of skis through the underground walkway of Angel Tube station in London before sliding down at rocking speed via the escalator.

"This is a dangerous, stupid and irresponsible act that could have resulted in serious injury or death to not only the individual concerned but also other passengers," LU said, according to 24dash.com, adding that strong action will be taken against those who try to perform similar attempt in future.

While the city officials are planning to charge the unidentified man, the stunt seems to have become a big hit over the Internet. Since posted, the video clip has attracted more than 20,000 viewers and some four-dozen comments, some suggesting the act as "madness" while others branding the man as a "dare-devil."
