Swimmers were swimming in the waters near Island Resort in Siu Sai Wan this morning when they saw an apparently unconscious man lying on a 4-meter-high reef at Cape Collinson. 

Although police and firefighters soon came after the receiving the report, a helicopter from the Government Flying Service was called to the scene to aid the rescue due to the strong wind and tide. 

The man was then pronounced upon further examination and his body was brought onto the rescue boat and sent to the pier opposite the Siu Sai Wan Sports Center. 

After preliminary investigations, officers found personal belongings in the man's backpack and identified the 65-year-old man, surnamed Wu. 

Officers also believed Wu accidentally slipped and fell to his death during his morning exercise. However, the actual cause of death has yet to be confirmed pending an autopsy. 

According to the swimmers, the man was found lying on top of an isolated reef 50 meters away from the swimming shed.
