A man has died after reportedly attempting a stunt which involved climbing onto the roof of a moving Paris metro train, reports International Business Times.
Police in the French capital believe that the 21-year-old was "train surfing", a craze which has slowly spread throughout major world cities.
The incident took place at around 7pm on Tuesday at the Bir-Hakeim Metro station, close to the Eiffel Tower.
Witnesses at the scene are reported to have seen the man on top of the train as it departed the station, but he hit his head on the roof and fell onto the tracks of the Bir-Hakeim bridge.
Speaking to news magazine L'Express, a British tourist said: "When the train started to leave the platform, he sat and turned his back on a low bridge that was approaching.
"He smiled at everyone on the platform. We then heard people screaming and he hit the bridge and was thrown from the train. There was a terrible thud as he hit the metal surface. It was terrifying."
Photographs taken at the scene later appeared to show forensic investigators walking along the bridge where the body fell onto.
The Service 6 line was disrupted for much of the evening while investigations were carried out at the scene.
The bridge is thought to be a popular place for daredevils to engage in "train surfing" due to the roofless section of the bridge which provides views over the Seine of the Eiffel Tower.
