RCMP in Nova Scotia are investigating the death of an infant after he suffered a cardiac arrest and died from his injuries Thursday night.

Police say they responded to a call from the Valley Regional Hospital on January 4 after a baby boy was brought in.

Six-week-old Ethan Chetwynd was suffering from cardiac arrest when he arrived at the hospital. He was then transported to the IWK Health Centre where he died last night.

An autopsy will be completed in Halifax this afternoon.

Police arrested two people on January 13 in connection with the infant's death, but they won't say what the relationship is between the pair and the child.

Candace Chetwynd, 21, of Port Hastings and 26-year-old Shawn MacIsaac of Waterville are facing charges of aggravated assault and failing to provide the necessities of life.

They were released from custody and are due to appear in Kentville provincial court on February 13.

RCMP say the investigation is ongoing.
