The probe by prosecutors in Thessaloniki will also investigate why police allegedly ignored instructions by a prosecutor to arrest PAOK owner Ivan Savvidis on the spot.
Federation Internationale de Football Association director for Europe Bjorn Vassallo said a delegation would travel to Athens later Tuesday to discuss the latest crisis, which began Sunday when the president of Greek club PAOK, Ivan Savvidis, stormed the pitch with a holstered gun strapped to his waist.
Fernando Varela had just scored in the 90th minute, putting PAOK ahead 1-0.
Savvidis, a Greek-Russian businessman with important holdings in Greece and rumoured close links with the government of Prime Minister Alexis Tsipras, has been on the run since an arrest was issued for his arrest on Monday. He said: "We are not going back, we will continue the fight for transparency and a better football". It said a failure to take action "to eradicate all sorts of violence" in the Greek league could lead to the suspension of the Greek association from FIFA. "I clearly had no right to enter the field of play in this fashion", Savvidis said in a statement.
"My emotional reaction stems from the widespread negative situations prevailing in Greek football lately and from all the unacceptable, non-sports related events that took place towards the end of the PAOK - AEK Athens encounter: the actions of the referee and his assistant (goal - offside - goal), the match suspension, the protests and invasion on the pitch by many people from both sides".
"I want to apologise to PAOK fans, to Greek fans and to the global football community", he said in a club statement. My only aim was to protect tens of thousands of PAOK fans from provocation, riots and human casualties.
"Believe me, I had no intention of interference with the opposing team or the referees". And Ι obviously did not threaten anybody.
Stratos said he had asked for the "quickest possible resumption" of matches but no date had been yet decided. So maybe Savvidis is protecting PAOK fans after all, just not in the way he claimed.
