SINGAPORE: A 20-year-old full-time National Serviceman died at the Singapore General Hospital (SGH) on Saturday afternoon.

Lance Corporal Mar Teng Fong, an engineering systems specialist, was found unconscious on the navy's RSS Persistence on Wednesday.

A fellow serviceman found him lying between a hydraulic sliding door and its door frame, after he failed to return from a routine check.

The Ministry of Defence (MINDEF) said Lance Corporal Mar was then taken to SGH in a helicopter where he was put in intensive care.

MINDEF added that he was given immediate medical attention on board the ship, which was out at sea for training.

A Singapore Armed Forces' (SAF) medical doctor and a medic continued to resuscitate him on board the helicopter.

MINDEF and the SAF extend their deepest condolences to the family, and are investigating the incident.
