An April Fool’s prank gone wrong Wednesday triggered a large police presence outside Churchill Secondary School after an incident at West 62nd Avenue and Heather Street. Shortly before 2 p.m., police received a 911 call regarding a potential robbery involving a group of men, including one wearing a mask and holding a gun. Witnesses stated they heard a woman screaming who was then driven away in a vehicle. Officers stopped the vehicle and removed four occupants at gunpoint. Police then learned the incident was staged. Police, who seized a paintball gun, haven’t recommended charges but parents of the suspects have been contacted and police school liaison officers are following up.
