“Detectives have launched an investigation into the death of a police and prison informant who was found hanged in his jail cell. The probe into Paul Day’s suicide, shortly after he told a solicitor he wished to retract false evidence he gave in a series of high-profile cases, including the 1996 murders of Lin and Megan Russell, raises the prospect of manslaughter charges and the possible unravelling of some major criminal cases.”
