MrDeadMoth livestream video game
A man will face court after he allegedly assaulted a woman at a home in Sydney's south-west while livestreaming to an online gaming site.

The 26-year-old was arrested at a home in Oran Park on Sunday night, three hours after he unintentionally streamed the attack and it was reported to police by fellow gamers.

His 21-year-old partner was not seriously injured but was distressed and shaken by the alleged assault, police said.

Detectives said two toddlers - one girl, 3, and another, aged 20 months - were in the home at the time.

The man was charged with common assault and granted bail to appear at Camden local court on Thursday. An apprehended violence order has been served.

The woman's mother told Channel 10 she was "very grateful" fellow gamers reported the 26-year-old to police.

"The community is showing that they care - and most of them, believe it or not, were men," the woman's mother said on Monday.

Channel 10 reported the woman was four months' pregnant with the accused's third child.

He was allegedly playing Fortnite and flew into a rage on Sunday night when asked to come out of his gaming room for dinner.

"Can you not? I said I'd be out soon," the 26-year-old said.

"No computer. I'm sick of this shit," his partner replied in the video of the incident posted online.

A sound could then be heard followed by a woman wailing before she said: "You fucking woman basher."
