The body of a baby was found in the Beetham landfill on Monday afternoon.
The child appears to be about three months old.
Before police arrived, a video recorded by someone at the dump had made its way onto social media platforms.
People recoiled at what the video showed, then many shared it on WhatsApp groups and among friends.
The body is that of an infant. There appears to be a large wound to the head. The child may have been dead for a few days.
The discovery was made by a landfill employee at around 1p.m.
Police suspect the body was brought to the landfill in a garbage truck.
The body has been taken to the Forensic Science Centre when an examination will be done to determine sex and cause of death.
