Protesters in Greece Wednesday evaded security at the Acropolis to drape giant pink banners over a wall near the Parthenon, demonstrators said.

One banner proclaimed “Resistance” in four languages while another called for mass demonstrations Thursday against the Greek government across Europe, The New York Times reported.

On Tuesday, demonstrators firebombed riot police headquarters in Athens and stormed a state television station to protest the police shooting of a 15-year-old boy on Dec. 6, Kathimerini reported Wednesday. A police officer was injured and six vehicles burned.

The protest has spilled onto school campuses, with an estimated 500 schools and dozens of universities under occupation by protesting students, the Greek newspaper said.

Meanwhile, a ballistics test on the bullet that killed Alexis Grigoropoulos and triggered the protests may contradict statements made by one of two police officers charged in the teen’s death, Kathimerini said. The results indicate the officer fired with his arm in the direction of the victim, not above Grigoropoulos’ head as a warning shot, which the officer claimed.
