A 27-year-old South Korean model on holiday in Singapore collapsed after downing too much alcohol in a short time at a KTV party. She died in hospital the next day.

Ms Kim Seoa was seen pouring 10 to 12 shots of alcohol into her glass and downing them in the wee hours of May 12, during a drinking game in which money was offered.

The model, who had a low tolerance for alcohol and did not usually drink, was found to have 310mg of alcohol per 100ml of her blood - a deadly amount almost four times the legal limit for drink driving.

Her final cause of death was certified as "acute alcohol intoxication".

Yesterday, a coroner's court heard that Ms Kim came here on a social visit pass in April and stayed with a Korean friend, who worked as a female public relations officer at The Prestige KTV in Merchant Road. On May 11 at about 11pm, she went to the KTV at her friend's invitation to join the birthday party of a customer, Mr Low Kok Hoong.

Guests sang, played pool, chatted and drank from bottles of brandy. At about midnight, a birthday cake was cut and two bottles of champagne were opened.

At around 12.30am, Mr Low's friend from Hong Kong, Mr Billy Kon, started a drinking game. He took out some $7,000 in $50 notes, and offered a note to the women for each shot of alcohol they drank.

Some of the female Korean guests drank straight from shot glasses, while others poured a few shots into brandy glasses before drinking.

Ms Kim joined in the drinking game, which was voluntary.

The game lasted about half an hour and she was seen sleeping on a sofa in a sitting position before lying down. Someone later spotted vomit coming out of her nose and mouth, and a friend cleaned her up.

Shortly after, at about 1.30am, her lips turned purple and she was unresponsive. The KTV's operations manager performed cardiopulmonary resuscitation (CPR), but stopped when she vomited again.

Paramedics arrived at about 1.40am and could not detect any pulse, breathing, or cardiac electrical activity on her. CPR was performed en route to hospital, where she died the next day.

Some 20 pieces of $50 notes were later found on Ms Kim.

Police found no evidence of foul play and believed that she succumbed to the effects of consuming "an excessive amount of alcohol at the KTV within a short span of time during the game with an enticing monetary offer", said investigation officer Fiona Lim.

State Coroner Marvin Bay will deliver his findings next Wednesday.
