Stevens was fishing close to the skate park just after 7pm on 12 March when he said he heard his son screaming, and the loud bangs and revs of a vehicle being driven quickly off-road.
He turned to see a man in a ute with children inside pull up on a footpath and feared the car had run over Elijah.
Elijah told Stevens he had been struck by the ute when the driver swerved in front of him as he attempted to ride along a footpath towards his father.
Stevens reported the incident to NSW police soon after and was visited by two officers at home later that night, but is yet to provide a formal statement.
Stevens said he believed he knew the identity of the officer, and said the skate park had CCTV cameras that may have captured part of the incident.
Tanya Day died in hospital on 22 December 2017 of a brain haemorrhage sustained when she fell and hit her head in the cells of Castlemaine police station 17 days earlier.
She was in the cells because she had been arrested for public drunkenness after being removed by police from a V/Line train from Bendigo to Melbourne.
