Murder charge in Sydney Qi Yu case

A man has been charged with murder after a 28-year-old Chinese woman vanished from her Sydney home more than four days ago.

Qi Yu was last seen by friends at a Campsie share house in the city's southwest on Friday evening and the following day police found her white Corolla in the nearby suburb of Burwood.

On Wednesday, NSW Police revealed a 19-year-old man had been arrested upon his release from hospital on Tuesday and charged with murder ahead of an appearance at Burwood Local Court.
