Police are questioning a man on suspicion of murder after a baby girl died in Wigan.
Greater Manchester Police said officers were alerted by medical staff on Thursday at around 2pm that a one-year-old child was being taken to hospital with head injuries.
She received urgent medical treatment, but died on Friday.
A 32-year-old man has been arrested on suspicion of murder and forensic teams have been searching a property on Fleming Court in the Shevington area of Wigan.
Detective Chief Inspector Jamie Daniels said: “All murder investigations are understandably upsetting, but when it involves a child as young as this it’s particularly distressing for everyone involved.”
He added: “We are currently trying to build a picture of what has happened in the lead up to this little girl’s death and how she has come to sustain her injuries.
“Specially trained officers continue to offer their support to loved ones at this terrible time.
“While this investigation progresses, we’d encourage anyone who might have information about this death to please contact us.”
