A 30-year-old man has been sentenced to five months in prison for assaulting a community nurse following a private prosecution brought by the NHS.
Amir Nowrowzi smashed a metal chair over Margaret Nelson's head and then shouted racist abuse at a receptionist at the healthcare centre for homeless people in Leeds.
Mrs Nelson, 58, suffered cuts and bruising and was left severely distressed by the unprovoked attack in July last year.
Nowrowzi was arrested at the time and released without charge, but former West Yorkshire Police detective Colin Wilson carried out his own investigation in his role as security manager.
Statements were taken from witnesses and a private prosecution was launched by the NHS Security Management Service.
Nowrowzi was found guilty of assault and using racially abusive language at an earlier hearing, and district Judge Roy Anderson, at Leeds Magistrates' Court, said: "You behaved in a dreadful way towards two ladies who were simply trying to help you."
He will probably be released from jail immediately because of the time he has spent on remand.
But the court heard his right to stay in the UK expired two years ago, and there are now plans to deport him back to Iran.
"I am a practice nurse in a prison for sex offenders. My colleagues and I are frequently subjected to verbal abuse & threats of legal action. This can be distressing & demoralising. We are trying to cultivate an environment where abuse is not tolerated but the daily grind of battling with some persistant offenders does take its toll on team morale. Such behaviour woud not be acceptable in general practice." - Anonymous
