The volleyball match between Olympiakos and Panathinaikos on Thursday evening ended in chaos.
A policeman was seriously injured by the riots between the fans of the two teams that are permanent rivals.
While the 31-year-old is fighting for his life, the General State Police is continuing with the arrests, which have reached 424 so far, to make it possible to identify the perpetrators.
The incidents and the very serious wounding of the policeman "escalated" the developments on many levels. The Panhellenic Federation of Police Officers and the Panhellenic Federation of Police Employees have issued a statement demanding the suspension of all championships in all sports.
In the statement, they express their anger and sorrow for the "murderous attack on their colleague", simultaneously asking Prime Minister Kyriakos Mitsotakis to stop immediately, today, all championships in every sport.
