Police in Berlin have launched criminal investigations into 25 people after forcibly clearing pro-Palestinian anti-war demonstrators from buildings at Humboldt University.
Officers briefly detained 169 people on Thursday night and took down their identities, a police spokeswoman said on Friday.
Police also took six further "measures restricting freedom" at a subsequent protest rally, and issued criminal summons to six additional people.
Pro-Palestinian activists had occupied rooms at the university on Wednesday in protest against Israel's ongoing war in the Gaza Strip, Germany's supply of weapons to Israel and in support of Palestinians.
Humboldt University management initially tolerated the protest and opted for a dialogue with the occupiers and academics.
But on Thursday evening, police cleared the occupied building.
Humboldt University President Julia von Blumenthal said the police operation was carried out under orders from Berlin's minister for research, Ina Czyborra, in agreement with Berlin Mayor Kai Wegner.
Student organizers denounced the police actions and accused officers of using unnecessary violence against students.
"The violent eviction" of the student protesters "marked by police brutality" as well as "the failure of the university authorities to protect their students" is a "grave injustice," the group Student Coalition Berlin wrote in a post to Instagram.
The group called for continued protests in solidarity with Palestinians.
Berlin police said they would provide additional information about the operation to remove the protesters later on Friday.
