Adelaide United Football Club CEO Sam Ciccarello confirmed the charges against Cornthwaite after the alleged incident, which took place just after midnight on Sunday 30 August 2009.

"It's alleged that Robert Cornthwaite was involved in an alleged assault very early this morning, at around midnight, at an Adelaide night club," Ciccarello said. "Robbie is being charged with basic assault and with withholding personal details from the South Australian police."

Cornthwaite was kept at a police watch house before being released a short time after the alleged incident, the defender to appear in the Magistrates Court on November 4, 2009.

Adelaide United has informed Football Federation Australia (FFA) of the alleged incident, Ciccarello saying the club is in the process of gathering further information before deciding on whether to enforce any sanctions on Cornthwaite.

"The club is already conducting a collection of information so we can determine if there has been any breach of the code of conduct. We've advised the FFA (Football Federation Australia) of the alleged incident and the FFA, through its disciplinary committee, will commence its own review of the information at hand as of tomorrow and will determine its position in terms of any code of conduct issues with the game itself and the player's behaviour," Ciccarello said.

"We're obviously very disappointed with Robbie that the incident has allegedly occurred, there's a fair bit of process still to take its course here...obviously Robbie is disappointed that he's put himself in a position that he found himself in, and we will commence a review process of the information and through our code of conduct will determine what actions will be appropriate."

Cornthwaite will join the rest of The Reds' squad as per normal for the club's training session tomorrow at 10.00am at Hindmarsh Stadium.
