Two security guards were injured by an explosion Thursday during an armed robbery inside a bank in north Edmonton. There was a confrontation between a suspect and one of the guards, Czerwonka said. Teamsters Canada, the union that represents the guards, said in a news release an improvised explosive device (IED) injured two guards. Police say two security officers were delivering cash to an ATM when an explosive device was detonated. Police responded to a similar case in September when an improvised explosive device detonated inside the vestibule of an RBC branch near 27th Avenue SW and 141st Street in southwest Edmonton.
