Anthony McMahon, aged 32, of Raheen Square, Ballinacurra Weston, pleaded guilty to assault causing serious harm to Dr Ananth Pullela at St Anne’s day care centre in Limerick on January 17, 2008.
The court heard that Dr Pullela, a distinguished forensic psychiatrist, may never work again as a result of the trauma he suffered.
McMahon also stabbed a psychologist, Dr Kathleen Burns, 64, after she went to Dr Pullela’s assistance. He was given a concurrent three-year sentence for the attack on Dr Burns.
Dr Paul O’Connell, a psychiatrist from the Central Mental Hospital, Dundrum, where McMahon has been held since the attack, said the accused still presented a serious risk of causing immediate and serious harm to others including his own family.
Passing sentence, Judge Carroll Moran said the attack was frenzied and savage and he had to take into account the danger McMahon presented to people and the fact that he had previously stabbed a man to death in another paranoid episode.
An application for leave to appeal was refused.
