Thunberg has also shared photos on Instagram of riot police entering a building where Students against the Occupation was holding a protest.
A Copenhagen police spokesperson said: “I can’t confirm the names of those arrested, but six people have been arrested in connection with the demonstration. They are suspected of forcing their way into the building and blocking the entrance.”
Recently Thunberg was arrested in Malmo, Sweden for protesting against Israel’s participation in the Eurovision contest in the city. Demonstrators held signs accusing Israel of “committing genocide” in the Gaza strip and claimed that "Eurovision celebrates genocide."
Students against the Occupation said in a statement posted on Instagram 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.”
Since last spring pro-Palestinian protests have set up encampments across universities around the US and Europe.
