His crude attempt to extort cash involved sending an email threatening to “go to the press” if he was not given £3,000.
Despite his actions, Mr Bambrick escaped being struck off by regulator the Nursing and Midwifery Council (NMC) in April 2013.
Instead, they imposed a suspension order and then two conditions of practice orders spanning a total of three years.
However, the NMC has now finally decided to ban Mr Bambrick from the profession because he had failed to show “insight” or “remediation”.
The saga started with the mental health nurse’s demoted from Band 5 to Band 2 on the pay scale following a series of errors at Crichton Royal Hospital in Dumfries.
He was so incensed at the prospect of losing up to £10,000 a year from his salary that he emailed a senior colleague with threats towards his manager, Ian Hancock.
The email read: “Encourage him to reinstate me band 5 and instruct Payroll to pay me £3,000 or I will take my story to the Standard.
“Pass this message on by Wednesday 1/06/2011.”
After the matter was reported, Mr Bambrick was hauled in front of a disciplinary panel with NHS Dumfries and Galloway, where he was immediately sacked.
The panel at his first NMC hearing ruled that the nurse would be suspended from the profession for six months – though this was later replaced by two successive 18-month conditions of practice orders.
The latest hearing, held in Edinburgh last week, was set up to review whether Mr Bambrick had complied with the order.
Mr Bambrick was not present at the hearing, where the NMC panel aired their concerns that he had not obeyed the conditions set out.
A decision notice, posted online, states: “The panel noted that the previous panels had concerns regarding Mr Bambrick’s level of insight and remediation.
“In the absence of any further insight or any steps Mr Bambrick may have taken to remediate his conduct, the panel cannot be satisfied that he has addressed the residual concerns of the previous panels.
“The panel therefore has concluded that the risk of repetition of Mr Bambrick’s misconduct remains which, in turn, gives rise to an ongoing risk of harm to patients and the public.
“Accordingly, the panel has concluded that Mr Bambrick’s fitness to practice remains impaired.”
The panel decided to remove Mr Bambrick from the register, and said that “a striking off order is the only order that will be sufficient to protect the public”.
The hearing notes also refer to a telephone call between the NMC and Mr Bambrick which took place on 23 February this year, in which the nurse suggested that he did not intend to return to nursing.
Mr Bambrick’s current employment situation is not known.
