A popular online trend led to a gun complaint and lockdown at a southern Alberta high school on Friday. Strathmore RCMP responded to a complaint of a suspect with a gun at Strathmore High School just before noon. RCMP told the school and other buildings in the area to initiate lockdown procedures. Police learned, after initial investigation, that there was never a threat to anyone, and the suspect was carrying a water gun. RCMP said they were participating in the “Senior Assassin” game, which has become a popular trend among graduating students across Canada. “Although an innocent game, RCMP is reminding those partaking, please be mindful that someone witnessing this or driving by could perceive a water gun to be a real firearm. Please be cautious and safe,” RCMP said in a news release. The online trend has recently been making headlines across Canada for all the wrong reasons. The Calgary Police Service issued a warning about the trend last week, saying it’s only a matter of time before a major incident occurs, with water guns getting confused for the real thing. The live-action game is typically played by senior high school students and involves players eliminating ‘targets’ during a set time period using water guns, spray bottles or other methods.
