A murder investigation has been launched and a woman arrested after the death of an 18-day-old baby in London. At around 7.30am on Saturday, March 14, officers attended Horseferry Road, Westminster, following reports that a baby had fallen from a height from a residential property.

A 43-year-old woman was arrested at the scene on suspicion of murder. She was taken into police custody, where she remains. The baby was taken to hospital, where she was pronounced dead. Detective Chief Inspector Alison Foxwell, who is leading the Met's investigation, said: "Our thoughts today are with the baby's family.

"The death of an infant is always an extremely tragic occurrence, and officers are making urgent enquiries around the circumstances.

"At this stage, we believe the incident occurred within a domestic context, but we are appealing for anybody with information to come forward."

Anybody who witnessed the incident is urged to call 101, quoting reference 1596/14MAR.
