A search is underway in bushland north-west of Sydney for a newborn baby murdered up to a decade ago.
The NSW Homicide Squad received information earlier this year that the baby was murdered not long after being born in late 2007 or 2008.
Police were told the baby was then buried on a rural property on the fringes of north-west Sydney.
Riot squad police and homicide detectives descended on a property on on Cliftonville Road at South Maroota on Tuesday morning to begin searching for the baby's remains.
Detective Chief Inspector Angelo Memmolo said police hoped the search could spark someone's memory.
"An investigation into the death of a baby will always be delicate and challenging for police and this incident is of great concern to us," he said.
"If anyone has knowledge about the possible murder of a baby around this time, please get in touch with us."
The investigation, named Strike Force Enact, has involved inquiries with the Department of Family and Community Services and NSW Health.
The search in South Maroota is expected to run over a few days.
