The Herald can reveal Roosters star Setaimata Sa was detained by police last night after he allegedly ran riot at a Sydney hotel after being refused entry for being too drunk.

He still made his way into the hotel, where he resisted police and needed to be physically restrained before being taken away.

Police said that Sa, a New Zealand international player, has been charged with assault, resisting arrest, malicious damage and failure to leave a licenced premises.

They told the Herald Sa was taken to Maroubra police station last night at about 10pm and will appear at Waverley Local Court on September 23.

Roosters chief executive Steve Noyce confirmed he had been made aware of the incident and would launch a full investigation today.

The incident will threaten Sa's league future, being the latest instalment in the Roosters' year of shame.

The most recent had been Roosters forward Nate Myles being suspended for six weeks over his drunken behaviour at a Central Coast hotel, where he defecated in a hotel corridor on a Sunday morning after attending a junior rugby league function.
