Lui, 20, appeared in Burwood Local Court on Monday afternoon and was refused bail.
“Burwood police have arrested a 20-year-old man in relation to allegations of a domestic violence-related assault on the weekend,” a police statement read.
“The incident is alleged to have occurred in the early hours of Sunday morning at an address in Abbotsford.
“A woman suffered facial injuries.
“The matter was reported to police later that day.
“The man has been charged with nine offences.”
The offences include two counts of assault occasioning actual bodily harm, three of common assault, one of malicious damage, one of choke with intent to commit an indictable offence, one of detain for advantage and one of aggravated robbery.
Lui recently put his good late-season form down to becoming a father for the first time.
He played a starring role in the Tigers’ run to third place on the NRL ladder before they bowed out 13-12 to St George Illawarra in Saturday night’s preliminary final.
The incident comes at the worst possible time for the league as it prepares for this Sunday’s grand final between the Dragons and the Sydney Roosters.
The Tigers stood Lui down on Monday afternoon but said he would fight the charges.
“Lui has told the club that he will vigorously contest charges laid against him,” the club said in a statement.
“The matter is now one for the police and the courts to manage.”
It said the club would respect the legal process and the rights of everyone involved by not entering into any further comment.
“Robert Lui has been relieved of his club duties until further notice so that he can properly concentrate his attention on the matters in question.
“Wests Tigers has an inclusive and family orientated culture and does not condone violence against women.”
The club said it would do everything in its power to respect the rights of all parties involved and offer appropriate support.
“Wests Tigers will continue to monitor this situation.”
