Police officers are thought to have arrested Indigenous people, usually male, for supposed drunkenness and/or disorderly behaviour, but sometimes without cause.[4] The officers would then allegedly drive them to the outskirts of the city at night and there abandon them in sub-zero temperatures.[5] At least seven such incidents have been claimed—three of which resulted in deaths—although there was only one case in which police officers were convicted of any wrongdoing. Four such incidents allegedly occurred between 1990 and 2000. A false report was made of such an incident around 2015, and another similar incident was claimed in 2018. Among all of these alleged incidents, only one conviction of police officers occurred, resulting in two officers going to prison for eight months.[4]
