A fire is believed to have been started at the home of Bikas on Wednesday (November 9) morning, causing severe damage to the property.

It has been reported that nobody was in the house in the region of Halkidiki in northern Greece at the time of the incident.

Both league and cup competitions have now been suspended until an investigation into the fire is finished.

"Following an extraordinary meeting, the EPO has announced its decision for the suspension of all National Football Championships until the conclusion of the investigation into the causes of the fire by the fire services," the EPO said. 

"The EPO expresses full compassion to Giorgos Bikas, who we will support in every way possible."

The incident at Bikas’ home follows the intimidation of another Greek football Refereeing Committee member, Giorgos Tsachilidis, who was threatened by two men at his home last week.

The start of the Greek season had already been postponed for two weeks in September because of a dispute over the selection of referees between Greece’s top clubs, the EPO and the Government.

A number of Greece’s highest profile teams have supported the decision to suspend competition, condemning the violence and calling on the Government to bring those responsible to justice.

"Olympiakos suffers more damage than most from this latest criminal and disgraceful act," the Greek champions said in a statement.

The suspension will not affect Greece's World Cup qualifier against Bosnia and Herzegovina in Athens on Sunday (November 13), which is to go ahead as planned.

Greece won the European Championships in Portugal in 2004, which is considered as one of the great sporting upsets.
