A Good Samaritan in Ohio saves the day when a routine traffic stop turns violent. 'Good Morning America' correspondent Jeremy Hubbard narrates the dash-cam footage in which an Ohio police officer was assaulted by an angry driver until, out of nowhere, a woman rushes to his aid. "Dayton police officer Jonathan Seiter pulls over this driver for a burned-out headight," Hubbard explains. "But things soon turn combative." In the footage, we see officer Seiter struggling with the driver on the roadside.

When the driver gains the upper hand, backup arrives. "But not who you would expect. That is a woman, a total stranger, a passerby saw the fight and decided to help," Hubbard reports. In a tag-team effort, Officer Seiter and the mystery woman deliver a lopsided beat-down on the driver until real police backup arrives on the scene.
