Australian Rugby Union have confirmed that they are looking into an alleged incident at Perth International Airport involving winger James O'Connor.
A statement released by the Australian Federal Police revealed that a 23-year-old man was escorted from the terminal in the early hours of Sunday morning.
It is alleged that O'Connor, who had played in the Wallabies' 14-13 win over Argentina in Perth on Saturday, was not allowed to board his flight because he was too drunk.
"Earlier this week, Australian Rugby Union was made aware of an alleged incident involving James O'Connor at Perth International Airport in the early hours of Sunday, September 15," read a statement from the ARU.
"While ARU had not received any formal notification, complaints or reports from police, airline or security officials, ARU began an investigation into the alleged incident. The investigation is ongoing."
O'Connor is currently without a club after being released by NRL side Melbourne Rebels.
