Former Wallaby Scott Higginbotham allegedly illegally entered a Fortitude Valley Police Beat and assaulted an officer after one of his friends was arrested for urinating in public Sunday morning.

The Australian Rugby Union confirmed that its integrity unit had launched an investigation into the incident at the Brunswick St Police Beat about 1.30am on Sunday.

Police said a 30-year-old man had been charged following an incident in Fortitude Valley and was due to appear in Brisbane Magistrates Court on February 21.

It is believed Higginbotham had dinner with his partner on Saturday night before meeting up with friends in the inner city suburb renowned for its eateries and bars. One friend was taken to the Police Beat after allegedly urinating in public and Higginbotham is believed to have followed him there. Higginbotham has been stood down from training until the police matter is resolved.
