Two players from Etoile were suspended from all competitions dating back to the incident. A player and an official from Hougang United received the same punishment.

Both clubs were docked five points and fined S$10,000 ($8,100), of which S$5,000 is suspended until the end of 2011.

"Both clubs engaged in acts of hooliganism which is both disgraceful and unprofessional of them," said Disciplinary Committee Chairman K Bala Chandran in a statement.

"We made the decision based on the facts and investigations that were done."

Football Association of Singapore President Zainudin Nordin said he was confident the disciplinary committee's verdict had been a "fair and just" one.

"I would also like to reiterate that the FAS has a zero tolerance policy on violence and will come down hard on any players or officials who put the game of football into disrepute," he added.
