Man held in Stepping Hill Hospital 'search for truth'
Police investigating the poisoning of patients at Stepping Hill Hospital have arrested a nurse on suspicion of tampering with medical records.
The arrest came as it emerged that a fourth death - that of an 82-year-old man on New Year's Eve - is being investigated.
Three people died and 16 others were affected by the contamination of saline at the Stockport hospital last summer.
The male nurse, 46, is being held over reports that medical forms were altered and a patient given extra medication. The individual was monitored by hospital staff and has since been discharged.
At this time the arrested man is being questioned in relation to these matters only, police have stressed.
Assistant Chief Constable Terry Sweeney said that officers were involved in a "search for the truth" in what was proving to be "an exceptionally complex investigation".
