The 2017 Edmonton attack was a stabbing and vehicle-ramming attack that occurred in Edmonton, Alberta, Canada, on September 30, 2017. Edmonton police constable Mike Chernyk was hit and stabbed by 30-year-old Abdulahi Sharif, who then struck four pedestrians with a rental truck during a police chase. All four injured survived and were hospitalized. The incident was investigated as a possible Islamist terrorist attack, with police confirming the presence of an Islamic State of Iraq and the Levant flag in the van that rammed the police officer. Sharif was convicted of eleven criminal charges including five counts of attempted murder, but was not charged with terrorism-related offenses.
