The nurse, a 63-year-old man, threatened to blow himself up in late October, 2009, on a tram in Gothenburg, western Sweden.
The police managed to wrestle the man to the ground, without the bomb being detonated.
The man later told courts that he had hoped to take his own life in the blast, or that police would have shot him dead when he threatened them with the bomb.
He was subseqently sentenced to probation and psychiatric care for unlawful threats and weapon offenses.
The Swedish National Board of Health and Welfare (Socialstyrelsen) since reported the nurse, claiming that he was unfit to work in the profession and that his “grossly inept” actions were likely to “affect confidence in him”.
However, the Medical Responsibility Board (Hälso- och sjukvårdens ansvarsnämnd - HSAN) dismissed the report this week, and has given the green light for the man to work again in his field.
“He suffered from a serious mental disorder the he no longer suffers from, and he has been well after the treatment,” said Aud Sjökvist, head of HSAN, to the Expressen newspaper.
When asked if people may be uncomfortable being treated by a nurse with such a past, Sjökvist was quick to point out that the man no longer suffers from his mental disorder.
“One must understand that he did this when he was sick. When he’s not suffering from the sickness, he has no problems,” Sjökvist told the paper.
Expressen wrote that the man, who was educated in Norway, plans to continue working abroad.
