More than 60 people were arrested on Wednesday while blocking traffic during a climate change protest near City Hall in Lower Manhattan, according to authorities and sources.

Nearly 150 protesters, some carrying signs reading “Tell the Truth” and “Non Violent,” rallied against climate change at the intersection of Centre Street and Park Row between City Hall and the Brooklyn Bridge around 10 a.m.

Some protesters lied on their backs underneath the stoplight at the intersection, stopping traffic for just over 30 minutes, according to photographs and witnesses.

At least two protesters climbed light posts and strung a banner, which read “Declare Climate Emergency,” over the roadway, photographs show.

Both people were charged with disorderly conduct and reckless endangerment, police said.

Sixty others were charged with disorderly conduct and issued desk-appearance tickets.

“They’re standing for something,” said protester Sylvia Alexandra. “This is what you have to do — the press pays attention to people getting arrested.”

Rebekah Berndt, an event organizer with Extinction Rebellion, the activist group behind the protest, said the arrests were “intentional,” adding that the group of people who were arrested had received instructions beforehand.

“We want to make sure people feel supported in getting arrested,” Berndt, 40, said. “For a lot of people, this is their first time doing any sort of civil disobedience.”

Also on Wednesday, three protesters with Extinction Rebellion were arrested after they glued themselves to a train in London’s Canary Wharf station.

Since Monday, London authorities have arrested more than 300 activists during Extinction Rebellion demonstrations.
