"a serious assault''.

And Police, who are investigating the assault, have arrested two people in connection with the incident which was reported by a social worker.

Police spokesperson Evelyn James Barnett said the baby -- who was yesterday listed in critical but stable condition in King Edward VII Memorial Hospital's Intensive Care Unit -- suffered multiple fractures to his skull, haemorrhaging of the cranium, a fractured collar bone, and multiple bruises to his head and body.

But she declined to release further details on the incident at this time.

The Royal Gazette , however, understands that at least one of the child's parents -- from a western parish -- has been arrested.
