Matches in all of Greece's professional soccer leagues have been suspended indefinitely after an official from the country's referees' committee was hospitalised following a violent attack.
The incident is the latest involving match officials in Greece being targeted with violence following bomb attacks in Cyprus.
According to police, 45-year-old former FIFA referee Christoforos Zografos was beaten with wooden clubs in the early hours of Friday by two men on a motorcycle in the area of Kolonos in Western Athens.
Zografos is the assistant director the Central Referee Committee, which appoints match officials and is headed by retired Scottish referee Hugh Dallas.
"After an emergency meeting of the Board of Directors, EPO has decided not to appoint referees from Monday (17/11) following the murderous attack on a member of the KED/EPO, hence the indefinite postponement of all matches in all divisions in order to protect those involved," EPO said in a statement.
Last month a small pipe bomb exploded outside the offices of the Cyprus referee’s association in Nicosia, while Football matches were suspended for a week in September after a fan died following an attack at a third division match in Crete.
A fire bomb was recently thrown at the home of an assistant referee in Limassol and earlier this year a bomb damaged the car of a prominent international referee and head of the association.
