An infant found with critical, non-accidental injuries has left all those involved "traumatised"

After the three-month-old was found by Police on Thursday night, the baby was immediately rushed to Masterton Hospital.

Detective Senior Sergeant Barry Bysouth says Police wish to thank everyone who, despite the distressing circumstances, have been fully co-operative with the initial investigation.

Police are in the final stages of their scene examinations at two Masterton houses and one vehicle today.
