Police given more time to question male nurse Police have been given more time to question a male nurse arrested on suspicion of tampering with medical records at Stepping Hill Hospital. Victorino Chua, 46, was arrested on Thursday by police probing the poisoning of patients at the hospital in Stockport, Cheshire. Detectives have obtained a warrant of further extension that is due to expire at 10.10am tomorrow, Greater Manchester Police said. Mr Chua was arrested at his Stockport home on suspicion of unlawfully administering or causing a person to take a noxious substance, or poison, after it was found that medical records were tampered with on Monday and a patient given incorrect medicine. Police stressed the suspect continued to be questioned only in relation to reports from hospital staff on Tuesday that medical forms had been altered overnight and a patient was given additional medicine. The suspect was held as it emerged a fourth death was being investigated. The family of Glasgow-born William Dickson, 82, a former journalist, of Cheadle Hulme, Cheshire, who died on New Year's Eve, have paid tribute to him. In a statement, they said: "Bill was a very kind and generous man with a great sense of humour. Police are investigating whether the poisoning Mr Dickson suffered at the hospital during the summer was a factor in his death. His is the latest death to be examined by officers investigating the contamination of saline drips in June and July last year, causing patients' blood sugar to fall in "hypoglycaemic episodes."
