The Australian Rugby Union is investigating an incident in which Wallabies winger James O’Connor was not allowed to board a plane and had to be removed from a Perth airport terminal.

O’Connor was due to fly to Bali with his girlfriend shortly before 5am on Sunday, the morning after the Wallabies won a tight 14-13 Rugby Championship Test against Argentina at Perth’s Paterson’s Stadium.

Australian Federal Police alleged he was intoxicated and not allowed to board the Air Asia flight. It is understood O’Connor has denied being drunk but admitted to engaging in a heated argument over the seating arrangements for himself and his girlfriend.

‘‘The AFP can confirm it spoke to a 23-year-old man at Perth International Airport in the early hours of the 15th of September (Sunday),’’ a statement from the AFP read.
