Shocking footage of a cyclist pushing through a level-crossing barrier moments before a speeding train arrives has been shared online by BBC presenter Jeremy Vine.
The aggressive cyclist is seen angrily lifting his bike over the safety barrier before barging through it himself moments after.
He can then be heard shouting "I don't f***** care mare" moments before the train's horn blares and he narrowly avoids being hit and killed as it speeds past.
The BBC Radio 2 presenter shared the shocking video, filmed at North Sheen station in south-west London on Twitter.
He said: "The level crossing at North Sheen today. Mate, the barrier is there for a reason.
"And when this jerk has to be scraped off the front of a train, the poor driver needs counselling for years."
British Transport Police said they are now investigating the "totally outrageous and dangerous behaviour", adding that the cyclist could have been killed.
