5:57 pm Flagstaff police received a 911 call from a person walking in the 2800 block of N 3rd st saying they could hear people fighting and a woman screaming for help. When officers arrived, they were able to locate the address that the disturbance was taking place. When they attempted to make contact, someone inside locked the door and refused to cooperate with Officers. Officers had to force entry into the home to check the welfare of occupants inside. They have cleared the house and at least one person is now in custody. Medics are also now being called to the scene for a female that is injured.
