The drone team arrived at the site near Block R at about 5pm and flew a drone to identify the entrance and exit route used by the killer to dispose of the child’s body.

The investigative team was also seen patrolling around the area where the body was found, and also interviewing some residents here, Bernama reported.

Two members of the unit flew the drone at a height of 30m for about 20 minutes in the area where the boy’s body was found, and over the bush area near the location.

It is understood that the drone was used to detect any “rat trails” or tracks in the area, Utusan Malaysia reported.

The investigative team also checked the vehicles parked around the apartment blocks to see if any had dashboard camera (dash cams) on board, in an effort to obtain any footage that could help in the investigation.

Zayn’s body was found in a stream near his residence last night, about 200 meters from his home at Blok R. The child’s death was reclassified as murder after an autopsy found injuries on his neck and body.

This morning, Petaling Jaya police chief Fakhrudin Abdul Hamid said a second statement had been taken from the parents yesterday, as well as a statement from the babysitter and the person who found Zayn’s body.

Selangor police chief Hussein Omar Khan said the police will also call up some neighbours in the area and the victim’s school.
