Video shows men assault, threaten metro Detroit grandma who was babysitting

Livonia police are looking for two men who assaulted and threatened a grandmother last month inside a home while she was babysitting her child. According to police, they believe this is not a random act because the men were let into a home by an acquaintance of the family. That woman who let them in has been arrested and charged for her involvement. In the video, you can see one man grab the grandmother and then threaten her, telling her not to call the police. Investigators believe the suspects may be from the Detroit or Warren area.
