Rush hour traffic was brought to a stand-still in all directions, when officers were required to secure most of the eight-lane intersection to investigate the accident. Investigating officers, as well as the involved officer, heard from their radios that three persons, in possession of firearms, bullet-proof vests, and a large sum of cash, had been arrested at the scene of the armed bank robbery without incident. Drivers caught in the traffic snarl heard only music and traffic reports from their radios, and remained unaware that they were victims of a bank robbery several miles away.
