ATHENS – The chief of the capital city's prosecutor's office is looking into an attack by a group of youths on Athens University of Economics and Business Rector Dimitris Bourantonis, with school violence not uncommon in Greece.

The group of about 15 hooded people screamed threates at him and hung a sign around his neck showing support for unlawful squatters before smashing computers and equipment and spraying slogans on walls and furniture, saied Kathimerini.

After running away as they always do, they posted a photo of the rector with the sign on his neck on an anti-establishment website but didn't say why he was targeted.

Anarchist groups are furious that Greek police have emptied squats, authorities saying some were used from criminal behavior.

Education Minister Niki Kerameus condemned the attack. “Those who think that with bullying, fascism and violence they will terrorize academics and go unpunished, they are badly mistaken. And those from the academic sector who show tolerance for the violation of the University asylum and academic freedom, must show responsibility,” she said in a statement.

Citizens Protection Minister Michalis Chrysochoidis said the perpetrators would be found although they usually aren't. The New Democracy government ended a law giving asylum on university grounds which had been used by criminals to hide themselves from police, a practice supported by the former ruling Radical Left SYRIZA that is riddled with hardcore anarchist and terrorist sympathizers.
