He was taken to Tan Tock Seng Hospital where he was pronounced dead at 3.30pm.
His grief-stricken widow, Madam Lim Choy Fong, 41, was struggling to cope with her loss when she spoke to The Sunday Times yesterday. The couple have a 17-year-old daughter and an 11-year-old son.
It was Madam Lim's daughter who rang to tell her that Mr Tan was in hospital.
Describing her husband as a devoted family man, Madam Lim said in Mandarin: 'I cannot believe that he had gone in such a manner. I never had a chance to say goodbye to him.'
