A MAJOR police manhunt is under way in Nundle near Tamworth on Wednesday afternoon.
Dozens of police were seen scouring the village and surrounds and were believed to be searching for a man as part of a police operation.
Police are remaining tight-lipped but the Leader understands the operation is connected to the ongoing investigation of the death of a baby in Aberdeen in the Hunter Valley earlier this week.
Hunter Valley police are in Nundle, backed by Oxley police including general duties officers, highway patrol, detectives and police on trail bikes.
Trail bike police are patrolling the village and several police cars have been seen coming and going from the station.
Oxley police declined to comment on the operation when contacted by the Leader.
A spokesperson for NSW Police confirmed the major operation in Nundle but would not be drawn on the details.
"A police operation is under way in relation to an ongoing investigation," the spokesperson said.
"No further details can be released at this stage."
On Sunday afternoon, a seven-month-old boy was rushed to hospital by his mother in Muswellbrook in an unresponsive state. The baby was unable to be revived by doctors and died in hospital.

On Tuesday, police made a public appeal for information as part of the investigation.
