Sungai Buloh police chief Hafiz Nor said the 19-year-old suspect was detained at 11.50am yesterday for suspected negligence under Section 31(1)(a) of the Child Act 2001.

“A post-mortem by a doctor at the forensic department of Sungai Buloh Hospital confirmed the cause of death was ‘neck injury due to canine mauling’, indicating a violent attack and bites by dogs,” he said in a statement today.

Police began investigating the case following a report lodged by a medical officer from Sungai Buloh Hospital.

An initial investigation found the toddler had been left in the care of his uncle while his parents were at work.

When they returned, they found the gate open and the child missing.

The boy’s body was discovered about 20m from the house, surrounded by several dogs.
