Police have launched a homicide investigation after a woman was found dead at a property in Congarinni, New South Wales. Emergency services were called to the home on Corella Close around 11 a.m. on Thursday following reports of an assault.

Officers arrived to find the body of a woman and a man who was allegedly armed with a knife. According to NSW Police Acting Superintendent Matt Hinton, officers confronted the man and arrested him after a struggle. The man sustained injuries to his neck and wrists, which appeared to be self-inflicted, and was taken to hospital under police guard in a serious but stable condition.

The woman, believed to be in her 70s, was pronounced dead at the scene by paramedics. She has not yet been formally identified but is believed to be the alleged attacker's partner. No charges have been laid as of Thursday night, and the investigation is ongoing.
