A woman has been arrested on suspicion of murder after an 18-month-old baby died following a fall from a sixth-floor window.

Officers were called to Barkerend Road, Bradford, at about 5.10pm on Saturday afternoon following a report that a child had suffered life-threatening injuries.

It quickly became apparent that the 18-month-old boy had died, West Yorkshire Police said.

Detective Superintendent Nick Wallen, who is leading the investigation, said: "This is clearly an extremely traumatic incident and specially trained officers are working to support the child's family members and those who witnessed what took place.

"It is no exaggeration to say those who witnessed this incident will have been deeply traumatised by what they saw.

"A 23-year-old woman has been arrested on suspicion of murder in connection with the baby's fall and she is currently receiving medical assessment in custody."
