A 22-year-old man and a 20-year-old woman have been arrested and are being questioned by detectives.
Officers from the Force Major Investigation Team are working to establish exactly how she died.

"The death of a child will always be greeted with shock and a deep sense of sadness. We have dedicated neighbourhood policing officers working in the area and talking to residents and I would urge anyone who has any concerns to speak to them."Reuse content
