Investigators are searching for a third suspect after an armed robbery at a bank in Courtice yesterday. The incident occurred at about 1:00 when two suspects armed with handguns, entered the ScotiaBank branch on Highway 2. The suspects made a demand for cash then fled the scene. None of the employees or customers were physically injured. Officers pursued the suspect's vehicle to the 401 on ramp at Stevenson Road in Oshawa. Police were able to stop the vehicle and box it in, however the suspect attempted to flee from police by striking their cruisers. At one point an officer discharged his firearm as the suspect drove towards him. The suspect managed to break free, and continued westbound on the 401 before losing control, and ended up in a ditch just east of the Salem Rd. off ramp in Ajax. The three suspects then fled on foot into a wooded area. At about 4:30, two suspects hiding in a residential neighbourhood near Miles Dr. and Wicks Dr. in Ajax were located. An 18-year old and a 17-year old were both arrested; the third suspect was not located. Anyone with information is asked to call Durham Regional Police.
