Staff at the hospital where seven patients died of saline poisoning were left stunned when they found a sinister message which read: “I will kill again.”
The words had been written on a bathroom mirror and became visible when it misted up.
A patient saw it and reported it to a nurse who alerted police.
The chilling message was found last week at Stockport’s Stepping Hill Hospital where seven patients have died of saline poisoning.
A police investigation into the saboteur is continuing.
Both hospital staff and detectives who are investigating the poisonings believe the message is a sick joke rather than a warning by the killer.
It is understood the message was found on a ward that is NOT among the wards where patients are thought to have been poisoned.
A statement from Greater Manchester Police said: “GMP is aware of a message that was found on a mirror in a patients’ bathroom at Stepping Hill hospital on Wednesday, October 24.
“It is believed the message, which was cleaned before officers attended, had been written in the preceding 24 hours.
“No offences have been identified and the hospital is dealing with the matter internally.”
A hospital spokeswoman declined to comment.
Detectives believe a rogue worker injected insulin into saline solution, poisoning 22 patients last June and July.
The deaths of Tracey Arden, 44, Arnold Lancaster, 71, and Derek Weaver, 83, are being investigated as murder.
Former M.E.N. news editor Bill Dickson, 82, Linda McDonagh, 60, John ‘Jack’ Beeley, 73, and Beryl Hope, 70, died several months after it is believed they were poisoned and tests are ongoing to establish the
precise causes of their deaths.
They are among a number of cases currently being treated as instances of grievous bodily harm.
Some 15 patients are believed to have been poisoned but survived.
Officers are also investigating the tampering of medical records at the hospital in January this year.
Former Stepping Hill nurse Victorino Chua, 46, a married dad-of-two, was arrested in January in connection with the deaths of three patients, the deliberate poisoning of 18 other patients and the tampering of medical records.
He has been released on bail until January while police carry out further enquiries.
