Environmental activist Greta Thunberg was arrested in Copenhagen by Danish police at a protest against the war on Gaza, reported a spokesperson for the student group organizing the demonstration. 

On Wednesday, six people were detained at the University of Copenhagen after 20 people blocked the entrance to a building, a police spokesperson said. 

The police did not reveal the identities of those arrested but a spokesperson for the Students Against the Occupation revealed that Thunberg was one of them. 

The news outlet Ekstra Bladet published a picture of Thunberg wearing what the newspaper said were handcuffs and a Palestinian kouffiyeh draped over her shoulders.

Meanwhile, Thunberg shared images on Instagram of the riot police entering a building where the students were staging a protest. 

“I can’t confirm the names of those arrested, but six people have been arrested in connection with the demonstration,” a Copenhagen police spokesperson said. “They are suspected of forcing their way into the building and blocking the entrance,” he added.

In a statement, Student Against the Occupation said that "while the situation in Palestine only gets worse, the University of Copenhagen continues cooperation with academic institutions in Israel." 

“We are occupying [the university’s] central administration with one demand: academic boycott now.”

Moreover, pro-Palestinian protesters have set up encampments at universities around the US and Europe since last spring to protest against "Israel’s" ongoing war against the Gaza Strip and its occupation of Palestinian territories.
