Police banned Extinction Rebellion activists from using boats, vehicles or “other structures” during the final day of its summer protests in London.
A condition was imposed upon the civil disobedience movement by the Metropolitan police on Friday morning in order to prevent disruption to communities.
Commander Jane Connors said: “The condition imposed today is limited and absolutely allows lawful protests to continue.
“My officers continue to engage with those exercising their right to protest.
“However, we need to balance this with the rights of those wishing to go about their daily lives, and action will be taken against those who choose to ignore this condition and/or break the law.”
Non-violent disruption by the movement resumed in the capital, Leeds, Cardiff, Glasgow and Bristol on Monday to urge the government to take immediate action to address the climate emergency.
The protest actions finished on Friday afternoon.
Repurposed and repainted boats, which are towed by vehicles, have become synonymous with the demonstrations.
On Thursday, Tim Whittingham, from Somerset, said his “jaw dropped” when he saw a boat he had sold on eBay being used by Extinction Rebellion outside the Royal Courts of Justice.
On Friday morning, Extinction Rebellion protesters blockaded the entrance to the construction of London’s £4.2bn super-sewer project as part of a fifth day of protests.
About 50 activists – including mothers and children from the nearby Riverside primary school – began a blockade to halt concrete pouring at Chambers Wharf in Bermondsey, southeast London, at 7.30am on Friday.
The movement argues that the continuous traffic and parking of mixing concrete lorries at one of the main sites for building the Thames Tideway tunnel will cause considerable air pollution.
Heather Mulkerrins, 31, who is protesting at the site with her four children – three of whom have asthma – said that she was there for the demonstration to “protect our children … I am worried about all the dust and pollution from the lorries”.
A spokesperson for Tideway, the company managing the construction of the tunnel, said: “The super sewer is a vital piece of infrastructure, under construction to clean up the River Thames from sewage pollution.
“We are aware of a protest outside our Chambers Wharf site. The police are in attendance and we are monitoring the situation to ensure the safety of our team and the community to minimise the impact on our vital work to clean up the River Thames.”
Police have accused Extinction Rebellion of causing “high-level” disruption and called for courts to hand out tougher sentences to deter activists from causing further disruption.
During 11 days of protests by the movement in the spring, 1,100 people were arrested – most of whom are expected to be taken to court.
