A Greek reporter probing match-fixing in the country's violence-ridden football league was hospitalised with facial injuries after a beating by unknown assailants, journalist unions said on Tuesday.
Aris Asvestas was ambushed outside his home on Monday by two men wielding brass knuckles, shortly after completing his radio show, the union of Athens daily newspaper reporters (Esiea) said in a statement.
"Aris Asvestas has extensively investigated match-fixing in football," the union said, adding that another three reporters have been attacked in recent months, without any arrests being made.
Asvestas had recently castigated the failure of authorities to punish clubs for recurring hooligan violence.
The union of sports journalists (Psat) said the reporter had been given eight stitches in hospital.
A number of football officials including two top division club bosses were placed in pre-trial detention last year after police phone-taps revealed the existence of a match-fixing racket, but the affair has yet to come to trial.
A UEFA report in 2009 also mentioned possible match-fixing in 13 matches of the second division and two Greek Cup matches, involving 12 clubs.
