More than 100 people have been arrested for taking part in ongoing climate change protests in London.
The number surged overnight after a police order came into force restricting demonstrations to a site at Marble Arch.
Groups lingered at other major sites including Waterloo Bridge and Parliament Square into the early hours of this morning.
It means 113 people so far have been detained over the Extinction Rebellion protest.
Transport for London warned that some roads in Westminster and the West End remained blocked as the rush hour approached.
Most of the arrests were for breaching the order instructing protesters to stay at Marble Arch.
Three men and two women were held on suspicion of criminal damage after protesters vandalised the energy company Shell’s headquarters on Monday.
Extinction Rebellion said it aimed to cause more than £6,000 of damage so they could be tried by a jury at a crown court.
The group confirmed more than 100 “brave rebels” had been arrested, some deliberately.
It tweeted that climate change protests took place in 33 countries on Monday, adding: “Day 2 starting, come and #RebelforLife.”
One of the protest organisers, Dr Gail Bradbrook, said: “The UN has given us until 2020 to change the course of humanity.
“If that doesn’t happen human extinction in my children’s lifetime is a possibility.
“People need to take their heads out the sand and look at the science and frankly panic and join us. It’s extremely frightening.”
She added that blocking bridges was necessary after other protests, marches and letters to MPs had achieved little.
“Nothing is being done of any real significance,” she said.
“Our demand is the government must tell the truth about the crisis we’re in. And that includes working with communities to build resilience.”
