Please help with assault , workplace violence, & bullying by management

Hello, I need some guidance and possibly representation on a workplace violence, harrassment, bullying, and assault issue. My daughter was physically assaulted at work by a member of the management team. The manager hit her multiple times in the face with a utensil, while other employees and customers observed. She tried to notify other members of higher managment but no one took her calls. So out of fear, she called me and I called the Police. Prior to the police responding, the Owner of the business called my daughter because he saw the incident on a remote camera. When my daughter told him the police were called, he reprimanded her and told her to downplay the incident and lie to the police because the incident may get in the papers and hurt his business. He also told her that if the manager was not allowed to work that it would be my daughters responsibility to find a replacement for the manager. The manager that hit my daughter left the business before the Police arrived and they are currently looking for her. Also, the Owner called my daughter a 2nd time and told her in no uncertain terms, that she was responsible for the entire incident. He offered her no support for the work place violence issue and and did not even come to the business to investigate. I know this sounds trivial, but it is a big issue for me and my family. The manager of the business and the business owner should be held responsible for ensuring a safe working environment. Can you please help? Thank you,
