At 8:10 am, a marked Fridley Police squad car was traveling southbound on University Ave at the intersection with Mississippi St NE. The officer was attempting to catch up to a semaphore violator, and the emergency lights were activated on the squad car. Eastbound and westbound traffic on Mississippi St stopped to yield to the squad car, and the officer proceeded through the intersection. An eastbound vehicle being driven by an adult male then proceeded through the intersection, striking the squad car. The squad car, a 2015 Ford Utility, overturned and landed on its roof. The officer, who was wearing his seat belt, had minor injuries and was transported to an area hospital. The driver of the other vehicle and his adult female passenger both complained of minor injuries. The passenger was also transported to an area hospital. The crash investigation will be handled by the Minnesota State Patrol. The initial semaphore violator was not identified and did not stop at the scene.
