ATHENS, Greece -- The Greek football federation has indefinitely suspended all league games after a suspected arson attack damaged a referee's home.

A federation statement said the cause of Wednesday's blaze at Giorgos Bikas' empty holiday home was "suspicious."

It said the federation will take further action once the fire department issues an official report.

Last week, Bikas had said that another senior referee was threatened outside his house by unknown men.

Greek football has been plagued for years by persistent fan violence and allegations of corruption and match-fixing.

The government briefly delayed the start of the top division in September, arguing that a festering squabble involving the federation, league organisers and clubs posed serious security concerns.
