Six Greenpeace protesters who scaled Britain's tallest building have been arrested on suspicion of aggravated trespass, Scotland Yard said.
The group of female activists reached the top of the Shard in central London after 15 hours of climbing in protest at oil drilling in the Arctic.
After reaching the summit of the 72-storey building, two of the campaigners unfurled a 32 foot by 32 foot blue flag with ''Save the Arctic'' written in white across it.
A Metropolitan Police spokesman said: "Six female protesters that climbed the Shard today have been arrested. They have been arrested on suspicion of aggravated trespass."
The activists reached the top of the building at around 7.10pm. They were later driven away by police in an unmarked white van to the sound of cheers from supporters gathered at the foot of the landmark.
The women, who evaded security guards early in the morning, said their climb was intended to put Shell and other oil companies in the spotlight.
A Shard spokesman said that in the interests of public and protester safety, the viewing platform of the Shard had been closed to visitors.
The building's emergency response team had advised that The View, the platform on floors 68, 69 and 72 which gives a view of London from 800ft (244m) up, should be closed with immediate effect, he added.
"We apologise to guests for the inconvenience caused and The View will be pleased to honour their tickets either later on today or on a different date," the spokesman said. All three restaurants and offices in the building remained open.
The demonstrators live-streamed the climb from helmet cameras, with birds-eye views of their ascent broadcast live at www.iceclimb.savethearctic.org.
