Some 600 friends, relatives and strangers turned up on Thursday afternoon to say their final good-bye to the two brothers who were killed in a horrific accident in Tampines on Monday.

As gospel music played, the coffins of Nigel Yap, 13, and his seven-year-old brother Donavan were carried out of the void deck of the family's Tampines Street 44 home into two hearses.

Following behind were their parents, Mr Francis Yap, 39, Madam Suliani Ang, 38, relatives, neighbours, friends and well-wishers.

They had earlier attended a 15-minute service where two pastors led the crowd in singing hymns and saying their last prayers.

The entourage is headed to Mandai Crematorium which will be the two brothers' final resting place.

The boys were killed when their bicycle was hit by a cement mixer truck at the junction of Tampines Avenue 9 and Tampines Street 45 on Monday evening.

The driver is currently out on bail and his licence has been suspended.
