A Melbourne teenager who died in "unusual circumstances" may have fallen from a roof, police say.
The 14-year-old boy was found by family members with head injuries in the driveway of a Balwyn home, in the same street he lived in.
An ambulance took him to hospital around 5am (AEDT) on Saturday, but he later died.
Paramedics had been called to reports of a fall.
Victoria Police Sergeant Graeme Rodgers said the death was unusual given where the teenager was found.
"It's unusual circumstances in which the young person has died," he told reporters at the scene.
"Very tragic. Young male, full of life, enjoyed his sports and for some unknown reason has tragically died."
A police spokeswoman said they are investigating whether the boy fell from the roof.
Forensic officers set up a ladder to the roof of the home's carport on Saturday morning and scoured the area.
Homicide squad detectives have been called in to help local police.
A post-mortem examination will be held later to determine a cause of death.The spokeswoman would not confirm media reports that the death is no longer being treated as suspicious.
