A MAN fell 12 storeys to his death on Saturday night while a fire raged in his flat where his two young children lay dead in their bedroom.

Neighbours in Ang Mo Kio Avenue 10 heard two explosions at about 9.50pm and saw thick, black smoke billowing out of the sixth floor unit in Block 543.

As some of them scrambled out of their flats and gathered at the ground floor, they looked up and saw Mr Ng Chee Kiang, 39, plunging from the parapet on the 12th floor.

Firefighters broke into the blazing flat and found the siblings lying face-up, side by side, on a bed in their bedroom. Neither had a pulse nor were breathing.

It is not clear how Xavier Ng Wei Yi, 5, and Cheryl Ng Shi Hui, 3, died. But their bodies were not burnt and the fire was largely restricted to the living room.

Early investigations show the fire appeared to have begun on the living room sofa.
