Initial investigations revealed Bhim Bahadir, 31, was supposed to have been working at another block and not the one where he had plunged to his death.

Putrajaya police chief ACP Rosly Hassan said: “The worker should not have been at the site where he fell.

“Moreover, the work schedule showed that yesterday was the victim’s day off. We are investigating why he was at the scene yesterday,” he said.

In the 8.50am incident yesterday, Bahadir was killed on the spot after plunging on a makeshift gondola and falling on a Bangladeshi worker who was in the gondola at the construction site of a new Malaysian Anti-Corruption Commission (MACC) building.

The Bangladeshi, Mohammad Abul Hosen, 45, sustained a broken right hand and was warded at the Putrajaya Hospital.
