2014 Sydney hostage crisis
The 2014 Sydney hostage crisis, also known as the Sydney siege and Lindt Cafe siege, occurred on 15–16 December 2014 when a lone gunman, Man Haron Monis, held hostage ten customers and eight employees of a Lindt chocolate café located at Martin Place in Sydney, Australia. Police treated the event as a terrorist attack at the time, but Monis' motives were subsequently debated. However, the findings of the Coroner in 2017 deemed the event to be a terrorist attack.
Sydney siege inquest
In Australia, an inquest is mandatory whenever a person dies during a police operation. The inquest was presided over by the New South Wales State Coroner, Michael Barnes, and its task was "to determine how the [three] deaths occurred, the factors that contributed to them and whether they could have been prevented".
