TWO 16-year-old schoolboys were found lying below a block of flats in the Eunos Link area early on Saturday.

One of the boys, Ku Witaya, was pronounced dead after paramedics arrived at 5.30am at Block 667 in Jalan Damai.

The other boy, Sia Chan Hong, Witaya's classmate at Tampines Secondary School, was still conscious. He was sent to Changi General Hospital but died at 7.50am.

Police said they had been alerted by a call at 5.20am.

The boys are believed to have fallen from the ninth storey, where Ku lived with his parents, younger brother, younger sister and grandmother.

It is believed that the two boys had been with two other friends in Ku's bedroom on Friday night till early yesterday morning.

The two friends later went out to buy food. On their return, they found the duo missing and later saw their bodies at the foot of the block. One of them called the police.

Ku's parents were at work when the tragedy happened.

His father is in the construction business and, according to neighbours, his mother is a factory worker.

Except for Ku's younger brother who was out at the time, the others in the family was asleep.

Police are investigating the cases as unnatural deaths.
