Hundreds of staff at a high security hospital are to stage a 24-hour strike in a row over the dismissal of two colleagues.
Members of the Prison Officers Association (POA) at Ashworth Secure Hospital on Merseyside will walk out from 7am on November 13, followed by other forms of industrial action.
The union, which has over 500 members at the hospital, said its members were "outraged" over the dismissal of two colleagues for restraining a violent patient.
POA members work as psychiatric nurses at Ashworth, where Moors murderer Ian Brady and police killer Dale Cregan are detained.

He will be sentenced on June 26.
Moors murderer Ian Brady has been returned to high security hospital after being treated for a fall.
The 76-year-old child killer was treated for two broken bones after an incident at Ashworth Hospital in Merseyside.
It was reported that he was taken to Aintree University Hospital under police guard.
He is now back on his ward at Ashworth.
A spokeswoman for Ashworth Hospital said: "Ian Brady, aged 76, who was admitted to a general hospital earlier this week on Tuesday for treatment for two broken bones suffered following a fall, has returned to his ward at Ashworth Hospital on Wednesday."
Brady, who murdered five children in the 1960s with his lover Myra Hindley, was jailed for life in 1966.
Last year he lost his battle at a mental health tribunal to be released from Ashworth on the grounds that he was no longer insane.
Moors Murderer Ian Brady is being treated for broken bones after falling at the high-security Ashworth Hospital.
The 76-year-old is believed to have fractured his hip and is being treated at an undisclosed hospital.
The Moors Murderer, Ian Brady, has written a 700-word letter in which he condemns a mental health tribunal's decision to keep him locked in a secure hospital.
Brady describes the tribunal as "£250,000 wasted by Ashworth medical mediocrities manipulating a politically motivated tribunal... designed to distract public attention from the lack of reasoned argument and pertinent evidence."
The killer sent the letter to Channel 5 News. In it, he criticises those who gave evidence: "'The pathetic petty abuse... rubberstamp witnesses employed to smear, discredit and distract, revealed more about Ashworth's collective culture of applied ignorance and malice than it did about me."
Brady continues by writing: "Those listening in the real world would have doubted their senses."
