Police in Berlin have launched numerous criminal cases after cracking down on a pro-Palestinian protest at Humboldt University on Friday.
Protesters at the rally on Friday chanted the slogan "From the river to the sea, Palestine will be free," a controversial phrase that Berlin police have sought to classify as anti-Semitic.
Police on Saturday said they opened 37 investigations on potential charges including incitement and resisting law enforcement officers.
A total of 38 protesters were detained by police at Friday's rally, police said.
Around 150 protesters gathered at the university on Saturday, and demanded the use of a lecture hall for talks, which university management had refused.
Protesters sought to formally register the rally with authorities on Friday but their request was denied.
Police ordered the protesters to refrain from anti-Semitic exclamations and began their crack down after the slogan "from the river to the sea" was chanted.
Protests against the Israeli's ongoing war in the Gaza Strip and in support of solidarity with the Palestinians in Gaza have been taking place at numerous universities in the United States for more than two weeks.
Students have also recently occupied university campuses across Britain in protest against the war in Gaza.
