SINGAPORE - In A rare tragedy, a Singaporean diving instructor and his student, also a Singaporean, both drowned in the waters off Pulau Tioman island in Malaysia on Saturday.
Quoting the operator of a Tioman diving equipment shop, Shin Min Daily News reported on Sunday that the victims could have run out of air while diving.
The dive shop operator, who was identified only as Mr Reynalds, 36, told the Chinese language evening daily that the pair had rented a tank each from him on Friday before they went diving.
He claimed that the men did not replace the tanks and used them again to go diving on Saturday, adding that perhaps they did not realise the amount of air they had left in their tanks.
There is also a possibility that they had run into problems inflating their dive vests to return to the surface, Shin Min reported.
The diving instructor has been identified as Mr Tan Seah Heng, 48, and his student as Mr Lee Yong Yeow, 35.
When The New Paper spoke to a veteran Singaporean diving instructor about the drownings, he was struck by the unusual circumstances of the tragedy.
For one, he was surprised by the claim that the victims had not replaced the air tanks from the day before.
Declining to be named, the 40-year-old, who has been a diving instructor since 1995, said that it was highly unlikely that the men had used the same tanks to go diving over two days.
Air tanks usually cannot last for a full day, let alone two, he said, adding: "Divers can safely go underwater when there's 200 bars of air in their tanks and usually resurface when there's 50 bars left for safety reasons."
He was also shocked that an instructor had drowned with his student.
"I've been diving since 1992 and in all my years of diving, I've never heard of a case of an instructor and his student dying in the same incident. In my experience, this is unheard of."
Another diver, who also requested anonymity, also said that he had never heard of such an incident in his 20 years of diving.
When TNP went to Mr Lee's wake at the void deck of a block of flats at Bedok Reservoir on Sunday evening, a family friend said that he was a researcher with the Agency for Science, Technology and Research (A*Star).
The friend, who declined to be identified, added that Mr Lee was married but did not have children.
"The tragedy came as a shock to everyone. He had a lot going for him. He was a good person. I'm very sad that he's gone," he said.
When TNP approached a woman who was being comforted by other mourners, one of her companions, a slim bespectacled woman said that it was "not convenient" for them to be interviewed.
Declined to comment
When TNP visited Mr Tan's condominium at Dover Rise near Buona Vista, a woman answered the intercom, but declined to comment on the incident.
The Star newspaper in Malaysia reported that the men had died during a diving trip off the island's Air Batang beach.
When they were found to be struggling in the water, other divers went to their aid and took them to shore at about noon on Saturday.
Assistant Superintendent (ASP) Zainul Mujahidin Mat Yudin, the deputy police chief of Rompin, Pahang, said the case has been classified as a sudden death.
"Initial investigations showed both victims and a woman were in a group diving in the site about 25m from the shore," he said.
Another Malaysian newspaper, the New Straits Times, identified the woman as Mr Lee's wife.
It quoted ASP Zainul Mujahidin as saying: "During the incident, the wife suddenly realised that her husband and their coach were having some kind of difficulties before she went up to the surface and screamed for help.
"Several individuals managed to bring the victims to the beach and some even tried to give CPR (cardiopulmonary resuscitation) to them, but it was just too late."
