A postmortem will be carried out later today after a three-year-old boy has died from an overdose of methadone, a drug used as a substitute to heroin. The boy has not been named.
The boy, who came from Leigh, near Wigan, Greater Manchester, is said to have taken the drugs from his mother's handbag. He was taken to Wigan Royal Infirmary, and then to Alder Hey Children's Hospital in Liverpool where he later died.
Police and Social Services are looking into the incident.
