Last month, a Citibank security guard obtained what Extinction Rebellion said was an unconstitutional restraining order against Rozendaal and another activist, Stop the Money Pipeline director Alec Connon.
According to the activists, the security guard claimed he was assaulted after hitting his head on a plastic pipe that demonstrators were using to block an entrance to the bank.
Rozendaal and Connon were warned that any violation of the restraining order could result in criminal contempt charges carrying a maximum sentence of seven years in prison.
"Over the last decade, Citibank has been the world's number one funder of fossil fuel expansion," Rozendaal said Thursday. "Yet rather than doing something about its role in the climate crisis, Citi is choosing instead to target climate activists with false charges and unwarranted arrests."
Thousands of people have rallied to demand an end to fossil fuel financing during two months of ongoing Summer of Heat demonstrations. More than 475 activists—including scientists, faith leaders, elders, students, and parents—have been arrested during the protests.
"It's alarming that Citibank is resorting to scare tactics to intimidate climate activists that are simply trying to get the bank to stop financing the fossil fuel industry that is killing our planet and polluting our communities," Democratic New York City Councilwoman Sandy Nurse said in response to Rozendaal's arrest.
"Citi should stop targeting activists and focus instead on ending its support for fossil fuels," Nurse added.
The Center for International Environmental Law, a Washington, D.C.-based nonprofit advocacy group, said that "the use of vague restraining orders to keep protesters away from Citi's New York headquarters represents a troubling effort to suppress these lawful demonstrations and mute advocacy for a just and sustainable world."
"Such measures not only threaten democratic freedoms and hinder crucial advocacy against environmental racism, but most importantly undermine efforts to challenge the financial underpinnings of the climate crisis," the group added.
New York Communities for Change climate campaigner Alice Hu said on social media that "it's wild Citi would have NYPD arrest the 63-year-old peaceful protester for *checks notes* playing the cello."
"But, ultimately unsurprising from the top funder of new fossil fuels since 2016," Hu added. "After all, the floods, fires, and famines that Citi funds are the epitome of violence."
Rafael Shimunov, who hosts the "Beyond the Pale" program on left-wing New York radio station WBAI, quipped, "Thank you NYPD and Citibank, our streets are so much safer without this 63-year-old cellist on them."
The Summer of Heat on Wall Street is set to continue next week, as immigration rights groups are planning to lead a "Migrants Grieve and Rage Against Climate Destruction" day of action outside Citibank's headquarters on August 13.
