Greg Knight, 29, of Spruce Avenue was arrested by Buffalo police as he was injuring a woman during an incident in her Sweet Street home late Sunday afternoon.
Knight was arrested as he was allegedly assaulting the woman on the floor of her home in the first block of Sweet about 5:10 p.m.
The woman was taken by ambulance to Erie County Medical Center for treatment of a large gash on her forehead. Knight was charged with second-degree assault, first-degree unlawful imprisonment, fourth-degree criminal possession of a weapon and second-degree obstructing.
Knight was accused of striking the woman with a glass bottle as the incident began and police were called after a neighbor reportedly heard the victim screaming for help, according to an arrest report.
