1993 Perth tank rampage

Hayes had a history of mental health issues, and previous encounters with the police over criminal behaviour, including charges of breaking and entering a delicatessen in 1987, stealing $78,000 worth of counter-terrorist equipment from the Special Air Service Regiment barracks in November 1992, and illegal possession of a firearm in April 1993. In 1987 he was forcibly admitted to the maximum-security wing of Graylands Hospital due to paranoid delusions, and treated for schizophrenia.

On the morning of 27 April, Hayes stole an Australian Army M113 APC (without ammunition) from the army depot. Some reports have alleged police abuse and harassment as the motive for his behaviour.[5] Hayes drove the APC through a fence and into the side of the Wembley police station at 4.40am. He then rammed a police van and drove towards the police headquarters in the CBD, where he smashed through the security gates and rammed six police vehicles, a motorcycle, and several private vehicles. He then caused damage to the CIB building before circling Parliament House, where police negotiators failed in efforts to get him to surrender.[6] Three special forces officers climbed onto the vehicle and dropped a tear gas canister into the vehicle, after which he was arrested following a struggle.[7]

The media coverage treated the event as a surreal and somewhat humorous event. When queried as to the ease with which the vehicle had been stolen, Brigadier Terry Nolan stated that "If you'd have asked me this yesterday I would have said it's not easy to do it, but the evidence of this morning would indicate that it's perhaps easier than I would have thought."[3]

In court Hayes claimed his actions where retaliation against the police for three attempts to kill him.[8] His defence was later rejected and he was sentenced to four and a half years in Casuarina Prison with the possibility of parole after 17 months.[9] He was diagnosed with paranoid schizophrenia. Hayes died in 2017.[10]
