Police probe death of diver off Sai Kung
From Simon Parry, SCMP
Friends suspect wealthy bar owner might have been hit by a leisure vessel in a busy bay
Police have launched an investigation into the death of a diver found unconscious with head injuries in a bay popular with fans of high-speed water sports.
They are investigating whether bar owner Bjorn Lohse, 51, was accidentally struck by a 'Zapcat' - fashionable dinghies with powerful outboard engines - or another vessel while diving off Lung Ha Wan, near Sai Kung.
Mr Lohse - who lived with his wife, Barbara, and 13-year-old adopted son Felix in a house overlooking the bay, and owned Le Jardin in Lan Kwai Fong - had gone diving near his yacht, Solitaire, which was anchored 500m offshore.
A highly experienced diver and sailor, Lohse left a marker buoy to alert vessels to his presence, but it is believed a Zapcat or another vessel may have struck him as he surfaced after his dive on April 8.
Lohse was recovered unconscious with head injuries from the seabed by friends two hours after he began his dive around 3pm.
The bay was busy with Zapcats, a jet ski and other vessels.
Lohse's distinctive, 100-year-old yacht, which has been in the family for nearly 40 years, was a popular meeting place for Zapcat owners and other friends when it was moored in the bay.
Although police are still investigating the death, the tragedy has raised concerns among the wealthy and tight-knit expatriate community living around the bay about the use of the Zapcats close to shore.
A dozen of the South African-invented dinghies, which have become hugely popular in the area over the past 12 months, are regularly used on the bay, although a number of other vessels were known to be on the water on the afternoon of Lohse's death.
'Nobody saw what happened, but we all feel responsible in some way for what has happened,' said one Zapcat owner. 'Bjorn was a lovely guy and Solitaire was a place where everyone would drop by and have a drink when they were out on the water.
'He was a tremendous character. Bjorn was a quiet man and he might say only eight things in the course of an afternoon, but you'd remember every word he said.'
He added: 'Nobody knows for sure what happened, but it definitely looks as if he was hit by a vessel of some sort. There may be a case for an exclusion zone close to the shore, although Bjorn was some distance out when this happened.'
Another resident wrote to the Sunday Morning Post describing Lohse as 'an experienced and very responsible man who knew how to behave in and on the water', and described his death as 'an accident waiting to happen'.
'The amount of Zapcats and jet skis in Lung Ha Wan has been increasing over the last year, not only causing a high level of noise pollution but also causing serious danger for other people using the bay,' she wrote.
'The reckless way in which the Zapcat owners speed around the bay is a far cry from nautical behaviour normally demanded when entering a bay. I feel a huge anger towards these people and wonder how many people will have to die before they change their behaviour.'
Mrs Lohse declined to discuss the incident.
Terry Floyd, a marine lawyer representing Mrs Lohse, said: 'There is a criminal investigation under way into this incident and it would be inappropriate for me to comment further at this stage.'
On Wednesday, 11 days after Lohse's death, a police spokesman told the Sunday Morning Post that the incident was being treated as a drowning and that there was no criminal element or any suggestion that he had been struck by a vessel.
In response to detailed, follow-up questions, however, a revised statement issued the next day said: 'Police are still investigating the case and we will conduct interviews with the concerned parties in the [next] few days.'
