The body of a newborn boy found at a recycling centre is likely to have been collected from a household bin, detectives said.
Cambridgeshire Police said that the infant, named Gabriel by medical staff, was discovered at the site in Ely Road, Waterbeach on November 29. The force said inquiries with recycling centre staff suggest it is "likely" that the baby came from recycling collected from household blue bins in Peterborough and its surrounding villages, March, Whittlesey, Melbourn or streets off Mill Road in Cambridge.
A post-mortem examination carried out on December 5 returned inconclusive results about how Gabriel died. Detective Chief Superintendent John Massey said: "We are still investigating this tragic incident and trying to locate the baby's mother to offer her all the support she needs."
