A disputed goal at the end of a Sunday’s Greek League game between leader AEK and title rival PAOK led to a pitch invasion by PAOK’s owner, Ivan Savvidis, who appeared to be carrying a gun.

Fernando Varela scored with a header in the 90th minute, putting host PAOK ahead 1-0. The referee signaled a goal but then seemed to disallow it for offside.

PAOK’s owner, businessman Ivan Savvidis, came on the field twice and was accompanied by bodyguards. On the second occasion, without the overcoat he was wearing before, Savvidis appeared to be carrying a pistol which was in its holster.

AEK officials claimed Savvidis threatened the referee during his first foray onto the pitch, before being pulled away.

The game was suspended and the stadium was emptied of fans. Adding to the widespread confusion, there were claims that the referee, Giorgos Kominis, had actually allowed the goal.

An official statement is expected from the Greek league.
