Greece has suspended its Super League football fixtures after the president of club PAOK Salonika stormed on to the pitch with a holstered gun to protest a disallowed goal.
Ivan Savvidis, accompanied by his bodyguards, confronted the referee in Sunday's match against AEK Athens with what appeared to be a handgun strapped to his waist.
His club had a late winning goal ruled out for offside.
The game was eventually abandoned two hours after the commotion and local police are seeking to arrest Savvidis.
The Greek government says all matches in the top flight league will be suspended until all sides agree to a clear framework of conditions and rules.
