Police are investigating a murder-suicide case in Tsuen Wan in which a 26-year-old man and a 42-year-old woman were found dead.

Just after 11pm last night, Police received a report of a man who had plunged from a height lying unconscious outside Block 2 of Tsuen King Garden. Ambulancemen certified him dead at the scene.

Police officers later found the woman, who had been stabbed to death inside the bedroom of a flat in the building. They also found a knife inside the flat.

The man and woman reportedly knew each other and Police believe the man jumped from the flat after he attacked the woman. The Tsuen Wan District Crime Squad is investigating the pair's relationship and the motive for the attack.

A post mortem will be carried out on Monday.
