The submerged four-wheel-drive in the Macquarie River at Eglington.
Police and witnesses worked frantically to release an 18-month-old boy trapped underwater when the vehicle his father was driving ended up on its roof in the Macquarie River near Eglinton late yesterday.
The man was uninjured but was unable to free the baby, who was trapped in the white four-wheel-drive that was almost completely submerged.
Bathurst ambulance inspector Rhys Dive said grave concerns were held for the child, who had been underwater for two to three minutes.
Bathurst police detective Inspector Lance McFawn said emergency services were called to the scene at around 4.15pm.
He said police were first to arrive and found the driver outside the overturned vehicle and a small boy still trapped underwater.
A number of police officers and witnesses entered the river and managed to free the child.
He was transported to Bathurst Base Hospital where measures were in place to airlift the little boy to Sydney. Inspector Dive said the baby’s condition was serious.
Inspector McFawn said from early inquiries it appears the driver was attempting to cross the river in his vehicle, however, investigations into the incident are continuing.
