Male Nurse Arrested During Hospital Saline Poisoning Probe

A male nurse was arrested by police investigating the poisoning of patients at Stepping Hill Hospital in Stockport, northwestern England.

Victorino Chua, 46, was arrested at his home in Stockport on Thursday.

The arrest came as it was revealed that the death of an 82-year-old man on New Year's Eve was also being investigated as his medicines were contaminated.

His is now the fourth death being investigated by detectives working on the inquiry.

After the contamination of saline drips at the hospital in June and July last year, Arnold Lancaster, 71; Tracey Arden, 44; and Alfred Derek Weaver, 83, all died.

Another 16 patients at the hospital are believed to have been poisoned but survived.

Police believe saline was deliberately injected with insulin.
