A thrill-seeker took his life in his hands when he decided to hang off the back of a moving tram in Sheffield.
Crouching low to avoid being spotted by the driver, the man is clearly seen holding on to the tram’s windscreen wipers and standing on the rubber bumper.
The tram surfer’s dice with death to gain a free ride was captured on video in Norfolk Park by Dale Pask.
And transport bosses are today warning of the dangers of the terrifying stunt, branding it ‘dangerous’ and ‘extremely irresponsible’.
Inspector Steve Askham,of South Yorkshire Police, said: “Not only could you seriously injure yourself, you are also putting other road users at risk.
“You could also take up significant time and resources of the emergency services, should your behaviour result in a collision.
“I strongly urge anyone considering behaving in this manner to think about the consequences.”
A South Yorkshire Passenger and Transport Executive spokesman warned someone could be killed.
He said: “We strongly discourage this reckless behaviour. It is not clever or funny and could lead to someone getting seriously hurt or worse.”
Stagecoach Supertram also condemned the stunt.
A spokeswoman for Supertram said: “This is very dangerous behaviour that should not be promoted.
“Safety is our absolute priority and this kind of stunt is extremely irresponsible.”
Tramsurfing is becoming a problem other cities across the UK, with increasingly more people putting their lives at risk.
Transport bosses in Manchester were forced to adapt their trams in 2000, after teenagers were seen clinging to the outside of moving trams, with a narrow metal ledge on doors being removed.
It has also been seen on Edinburgh’s new tram network, which only celebrates its first anniversary later this month.
Hundreds of people are killed each year in countries such as Brazil, Russia and India clinging to trains, either by being hit or falling off, or by being electrocuted by high-voltage wires.
Anyone that witnesses tram surfing in Sheffield is urged to report it to the tram driver at the next safe location, or at travelsouthyorkshire.com/safe
