LONDON—A British female healthcare worker has been arrested on suspicion of murdering eight babies and trying to murder six others after an investigation into deaths at a neonatal unit in northern England, police said on Tuesday.
The arrest came after an inquiry into the deaths of 17 babies and 15 “non-fatal collapses” between March 2015 and July 2016 at The Countess of Chester Hospital’s neonatal unit.
