A 32-year-old man drowned while swimming yesterday at Sai Kung, where he had gone on an outing.
The man, Tsang, had left a Sai Kung pier with friends at around 10am, and about an hour later the party stopped some 200 meters off the shore of Tsam Chuk Wan.
Tsang and a friend dived into the sea and swam away from the boat. But the friend lost sight of Tsang after they had gone out around 200 meters.
The friend looked around but could not see Tsang and returned to the boat to seek help.
The 56-year-old boat owner, Cheung, alerted the police at 11.07am after looking for Tsang for a few minutes.
Rescue divers and paramedics from the Fire Services Department then boarded a police launch to start a search.
Joining the search soon after was a Government Flying Service's Super Puma helicopter and another Fire Services boat from Central.
Tsang was discovered floating at around 1pm by officers on the fire boat.
He was retrieved and taken to shore and an ambulance took him him to Tseung Kwan O Hospital. But he was declared dead on arrival.
The police said there were no suspicious circumstances surrounding Tsang's death and the cause of his death was to be confirmed with a post-mortem examination.
Tsang's family members rushed to the hospital after hearing about his death.
His young daughter cried and said repeatedly "I want dad."
In another incident, a father and his two sons were thrown into the sea while canoeing at Sai Kung at 1.10pm yesterday.
They had ridden canoes from She Ha Beach but were all tossed into the sea when they were struck by a big wave as they arrived off Pak Ma Tsui.
Marine police and Fire Services personnel combined in a search for them after receiving a report from a woman just after 1.20pm.
All three were found soon enough and taken to the shore. None of them had suffered injuries.
