The child, aged one, was airlifted to Royal Manchester Children's Hospital for treatment.

Police are investigating and say they are trying to track down several people who stopped to help the baby outside a home on Heap Street.

DI Mark Saunders said: "First and foremost, my thoughts are with the family at this distressing time.

"We know following the incident, there were people who thankfully stopped to help. We're really keen to identify those individuals and speak to them to find out what happened".
