Video: Nurse arrested in murder probe after hospital sabotage
A nurse has been arrested on suspicion of murder by police investigating the deaths of three patients at an NHS hospital in Britain.
The 26-year-old woman was being questioned by Greater Manchester Police after the deaths thought to be caused by the contamination of saline containers.
Detectives were called in after an experienced nurse reported a higher than normal number of patients on her ward with "unexplained" low blood sugar levels pointing to the saline ampoules being sabotaged.
Officers found insulin had contaminated a batch of 36 saline ampoules in a storeroom close to ward A1 of Stepping Hill Hospital in Stockport.
The unexplained deaths of Tracey Arden, 44, George Keep, 84, and Arnold Lancaster, 71, are all being linked to the deliberate contamination of the saline solution.
They are among a total of 14 patients whose treatment since July 7 is being examined by police.
One of the victims is still fighting for his life.
Meanwhile an alert has been issued telling hospitals across the north west to look out for any "unusual events or patterns".
An NHS spokesman stressed there was no suggestion the person being hunted for tampering with saline solution at the Stockport hospital was operating elsewhere.
