Brazilian club Vasco da Gama have been ordered to play home matches behind closed doors after a fan was shot dead during disturbances at their ground.
Vasco's 1-0 defeat on Sunday at home to title-chasing Flamengo in the Rio de Janeiro derby was marred by crowd trouble at the final whistle.
Liverpool midfielder Philippe Coutinho, a former Vasco player, was at the match as the club's guest of honour.
"I needed to apologise on behalf of Vasco," president Eurico Miranda said.
"What happened here is not Vasco. Do not qualify these people as fans. They are vandals, bandits. I'm not giving an explanation, but I'm sure it's something that was already prepared."
The Brazilian Football Confederation (CBF)
said that Vasco's fans caused "serious
disturbances and a show of violence". The
governing body added that an official inquiry
into the disturbances has been launched by
Brazil's Superior Court of Sporting Justice.
