Man spotted climbing The Shard this morning before being arrested on suspicion of trespassing

A man was spotted climbing The Shard this morning (Sun) at 6am before being arrested on suspicion of trespass.

Police said a 21-year-old man has been arrested – with two other men taken into custody under suspicion of ‘causing a public nuisance’.

The climber, believed to be Adam Lockwood, posted a terrifying picture of himself balancing at the top of the 310 metre (1,018ft) high building - the third tallest skyscraper in Europe.

In the image, the shirtless daredevil can be seen leaning against the top of the iconic skyscraper as it towers over the capital.

Video taken from the ground showed a figure scaling the outside of the building, making his way up one of the top points of the mega structure.

The Shard is the tallest building in the UK and Western Europe – and the UK's second tallest free-standing structure.

The suspected climber had previously completed climbs of other huge structures including Dubai’s second tallest building, Marina 101.

He posts pictures of his daredevil climbs to social media where commenters leave messages of support.

A railway worker who captured some ground-level footage of climb, told how the climber scaled the building in around an hour and 20 minutes.

They said: "I go to work at 5.50am and at that time it was already happening - I think he started climbing at 5.40am.

"I took the video at 6.45 and he reached the top at 7am. That stuff gives me the heebie-jeebies and it's not a bit of me, no.

"All of us were watching thinking 'what if he falls' - we were working and if he fell we would have to deal with the fall out so we were hoping he would make it to the top.

"When you get to the top there's a platform you can get onto and the police were there waiting for him.

"Half the station had to be closed as he could have fallen in a number of different places.

"He got to the top and we got a call at 7.20am saying he'd been arrested and we could open up the station."

A spokesman for the Metropolitan police said: “Officers were called at 5.38am on Sunday, September 4 following reports of a climber on the Shard.

"Officers, London Ambulance Service and London Fire brigade all attended. A number of cordons were in place while emergency services responded to the incident.

"A 21-year-old man was arrested on suspicion of trespass. Two other men were both arrested on suspicion of causing public nuisance."
