Canadian police have arrested a man on suspicion of lying about having joined Islamic State and committed execution-style killings, charging him with "hoax-terrorist activity", authorities said late on Friday. Starting in 2016, Shehroze Chaudhry, made social media posts talking about his role with Islamic State and also gave several media interviews but a Royal Canadian Mounted Police investigation found the 25-year-old had no links to the group. "The charge stems from numerous media interviews where the accused ... claimed he traveled to Syria in 2016 to join the terrorist group ISIS and committed acts of terrorism," the RCMP said in a statement.
