A man has been arrested after a 12-hour rooftop standoff with police on the 27th floor of a building in Sydney's north shore on Monday (9 October).

Following the discovery of a woman's body in the adjacent alleyway on Brown Street near Chatswood train station, the man appeared on the ledge at 6.30am local time (8.30pm BST, 8 October) and was seen dangling his legs over the edge while looking down at the crime scene tent.

New South Wales police finally convinced the man to return to their custody, with the aid of a Korean interpreter, at 7.20pm.

Both the woman and the man are believed to be in their 30s, and police are reportedly investigating a domestic violence incident, according to News.com.au.

Images posted by local media showed the man with his shoes removed on the awning of a 26th floor balcony for the building's communal gym.

A witness who discovered the woman's body in the alleyway told the Daily Telegraph Australia that he initially thought the woman was asleep, but soon realised she was dead.

"There was blood coming out of her face," Luke Bladen Williams Hamilton told the paper, adding that her body was cold. "There was blood smeared on the wall. So either she walked there and fell over and touched the walls, or somebody else had touched her."
