NRL star Semi Radradra is alleged to have assaulted his former partner numerous times over an eight-month period dating back to 2014.
Police are investigating the accusations after his ex-partner, Perina Ting, made a statement at Rosehill police station on Tuesday.
Ting has applied for an apprehended violence order against Radradra.
"A 26-year-old woman attended Rosehill Police Station, and reported that her partner a 24-year-old man, assaulted her on a number of occasions between September 2014 and April 2015, at their home in Parramatta," NSW police said in a statement.
The latest revelations come after the 24-year-old was a no-show at Parramatta training on Wednesday and was instead granted yet another extension on his Fiji holiday to deal with personal issues.
