A magistrate has intervened to enter not guilty pleas on behalf of an accused paramedic attacker, sending his case to trial. Mohamud Ali appeared before the Melbourne Magistrates Court on Thursday where he was committed to stand trial in the Supreme Court for the alleged attempted murder, intentionally cause injury and assault an ambulance worker. "It would be remiss of me not to get him assessed," she told the court. "I'm told there are issues which persuade me to enter a plea of not guilty on your behalf," she told the accused. The alleged attack in Reservoir has been a catalyst for further reform of laws protecting emergency service workers.
