Riot police officers entered the grounds of Thessaloniki University on Thursday evening, during scuffles that broke out during a protest rally marking a student uprising in 1973 that led to the fall of Greece’s junta.
It the first time security forces have been permitted onto a university campus since the early 1980s when a law was passed banning them from institutions of higher education without the prior permission of a prosecutor. The law was repealed in August as part of a broader education overhaul.
The officers entered the grounds of the Aristotle University after a group of demonstrators they had been chasing took refuge in one of the university faculties. Police detained one of the youths for questioning and swiftly withdrew from the university grounds, witnesses said.
