SINGAPORE - A three-month-old infant was sent to hospital after she was trapped in a car for at least 20 minutes on Sunday (Oct 11) afternoon.

Full-time national service man Muhammad Rykal Hannafi, 21, had first alerted citizen journalism website Stomp to the incident at the open-air carpark beside Block 537, Pasir Ris Street 51.

Mr Rykal, who lives on the second floor in the opposite block, had heard a commotion at around noon and went out to investigate.

"I saw several Singapore Civil Defence Force (SCDF) officers huddled around a black car. A baby was in it and the parents were also standing calmly nearby," he said.

It is not clear how the baby got locked in the car.

The Straits Times understands that a locksmith was called in by the parents to unlock the car door.

"The baby was inside for about 20 to 30 minutes, but she was not crying when the officers carried her out," Mr Hykal said. "She was then put in an ambulance."

An SCDF spokesman said the infant was conveyed conscious to KK Women's and Children's Hospital at around 1pm.

It received the call for assistance at 12.28pm and dispatched a red rhino and an ambulance to the scene.
