NRL player's ex-girlfriend arrested following a revenge porn attack.

The ex-girlfriend of a rising NRL star has been arrested following a shocking online tirade in which she allegedly threatened his life.

According to The Daily Telegraph, Brittany Hura posted a naked photograph of former partner and Penrith Panthers player Bryce Cartwright to Facebook, along with screenshots of explicit text messages they’d exchanged and an expletive-laden video in which she said he would “be dead soon.”

Hura was taken to Paramatta Police Station yesterday afternoon where she was charged with using a “carriage service to menace/harass or offend and stalk/intimidation with the intent to fear physical harm”.

The 24-year-old’s video, which has since been deleted from social media, showed her looking into the camera and addressing Cartwright with a slew of threats.

“You’re going to be dead soon, bro. Yeah, in the grave even. Six feet under, bro. Six feet under. You don’t even know what’s coming at you,” she said according to footage published by The Daily Telegraph.

“Don’t even take this as a threat, bro. It’s not like I’d be doing it. Don’t worry about me – I’ll be somewhere, on CCTV, so…”

The video followed a string of social media posts in which Hura appeared to be accusing Cartwright of cheating.

"You can call me a slag, crazy, psycho, liar or bitch. But is that honestly fair?" she wrote on Facebook last month.

"NO! I will not stand for this. Women deserve more than this. We deserve respect. If you cant respect your woman then have the decency to leave."

The pair were reportedly in a relationship for six years before splitting in 2011.
