Three prison officers have been injured at a regional Western Australian prison while breaking up a fight involving notorious murderer Valerie Parashumti.
Parashumti and her lesbian lover Jessica Stasinowsky were sentenced to a minimum 24 years' jail in March 2008 for the murder of 16-year-old Stacey Mitchell in December 2006.
Both pleaded guilty to bashing Stacey with a concrete block and strangling her with a dog chain because she annoyed them.
The pair kissed over her body before disposing of it in a wheelie bin, mimicking Stacey's English accent and filming the blood stained crime scene on a mobile phone.
A spokesman for the WA Prison Officers' Union said that over the weekend, three officers at Greenough Regional Prison, 420km north of Perth, were injured after intervening to stop a fight between Parashumti and another prisoner.
The three injured officers all required medical attention after being attacked and punched in the head while breaking up the fight between the prisoners, WA Prison Officers' Union Secretary John Welch said.
All suffered bruises, scratches and cuts in the intervention and all three were off work as a result of their injuries.
"This is a perfect example of the risks our members face at work every day," Mr Welch said.
"All of them had to receive medical treatment, and they are still shaken."
The injuries come amid a campaign by WA prison officers calling for a five per cent pay increase next year and highlighting the risks of the job.
The union also wants increased funding to the WA prisons system to deal with record numbers of prisoners, new facilities to address the overcrowding, and an increase in staffing levels.
WA's Department of Corrective Services has been contacted for comment.
