Catania have been ordered to play the rest of their home matches this season at neutral venues and behind closed doors as punishment for the hooliganism that resulted in a policeman dying at a Serie A match this month.
The ban on the Massimino Stadium will last until June 30. Catania were also fined 50,000.
Italian policeman Filippo Raciti was killed outside the ground during rioting involving fans from Catania and local rivals Palermo.
A statement on the Football League’s web site said the ban reflected “the gravity of the events and the real danger posed by these acts of violence” that had left an “indelible mark in the memory and the collective consciousness”.
The punishment also took into consideration “the absolute uselessness of sanctions already inflicted on Catania for previous acts of violence by its supporters.”
Last September the club was fined and ordered to play two matches behind closed doors after its fans fought with supporters of Messina and Palermo.
