A free climber was spotted scaling The Shard this morning, reportedly without climbing equipment.
The man was seen on the side of the London skyscraper at around 5.15am today, with onlookers sharing footage of the climber on social media.
Police spoke to the climber after the stunt, but he was not arrested.
The Metropolitan Police said: "Police were called at 5.15am on Monday July 8 following reports of a 'free-climber' on The Shard.
"Emergency services attended and the man went inside the building where he was spoken to by officers. He was not arrested."

Onlooker Rebeca Newnes spotted the climber from her neighbouring office.
"I saw police cars and around 15 people staring up at the building," she told talkRADIO.
"I saw an arm, I didn't know if he was cleaning the building or not, but I just got a camera out and started filming."
"It didn't look like he had equipment."
It is not the first time climbers have tarageted the 310-metre (1,017ft) building.
YouTuber CassOnline climbed from the public viewing platform to the apex in 2017, and in 2013, a group of Greenpeace activists also scaled the building to protest against oil drilling in the Arctic.
The previous year, The Shard secured a High Court injunction against Alain Robert, the climber nicknamed the French Spiderman, to stop him attempting to scale the building.
