Bystanders filmed the man as he clambered up the Leadenhall Building - commonly known as the "Cheesegrater" - on Friday morning.

He appeared to have no safety equipment as he scaled the 225m-tall (738ft) skyscraper

Police said the man was confronted by officers upon reaching the roof, before being detained.

Chief Inspector Tom Fisher, of City of London Police, said: "A man has been arrested for aggravated trespass after climbing up the Leadenhall building in the City.

"We were called at 9.06am and quickly put a cordon in place.

"He was met on the roof by police officers and taken into custody."

The Leadenhall Building is the sixth tallest building in the capital city.

In June, a British man was arrested more than halfway up the world's fifth tallest building in Seoul, South Korea, while attempting to climb to the top without safety ropes.

The 24-year-old was forced to abandon his attempt when he was intercepted by the authorities at the 73rd floor of the 123-storey Lotte World Tower.

He was forced into a maintenance cradle before being taken inside the building.

The climber, wearing shorts, had been making his way up South Korea's tallest skyscraper for more than an hour as police and fire crews gathered on the ground below.
