Brighton siege, Melbourne

On 5 June 2017, Yacqub Khayre shot dead Nick Hao, a 36-year-old receptionist at the Buckingham serviced apartments in Brighton, Melbourne. He held a woman hostage, an escort worker he had called to the building, and three police officers were wounded before police shot him dead. The woman escaped unharmed.

Shortly before the shoot-out, Channel 7's newsroom received a call from a man who said: "This is for IS. This is for Al Qaeda." Islamic State's Amaq outlet later called him one of its "soldiers". Victoria Police chief Graham Ashton said there was no evidence he was acting on a message from overseas.

Khayre was on parole at the time and wearing an electronic monitoring device. In December 2010 a jury had acquitted him over the 2009 plan to attack Holsworthy Army Barracks, for which three other men were convicted. A coronial inquest later examined whether he was properly monitored on parole and whether the attack could have been anticipated or prevented.
