He went to his car parked at Raffles Hotel and fell asleep in his car. He woke at about 1am to 2am and started to drive home. He was driving at an excessive speed along the ECP when he caused the fatal accident which resulted in injuries to the driver and two other passengers.

He fled after the accident and drove to his workplace, a restaurant in Frankel Avenue. He surrendered himself at 8am at Traffic Police headquarters. His breath-alcohol level was 42ug per 100ml of breath, 7ug above the legal limit.
