(LONDON) — British police arrested a female health care worker Tuesday on suspicion of murdering eight babies and trying to kill six others at a hospital neonatal unit in northwestern England.
Detectives began investigating the deaths of babies at the Countess of Chester Hospital in Chester more than a year ago, after the hospital reported a higher than expected mortality rate, which it could not explain, on the unit that cares for premature babies and infants needing special care.
The hospital asked police to “rule out unnatural causes of death.”
The investigation initially focused on the deaths of eight babies. Police said Tuesday that the force is now investigating the deaths of 17 babies and 15 “non-fatal collapses” at the unit between March 2015 and July 2016.
