WEST ALLIS, Wis. (CBS 58) -- West Allis police say they've taken a knife-wielding suspect into custody after using non-lethal force Monday afternoon, July 20.

Officers responded to the area near 76th and Orchard around 2:20 p.m. after a caller reported a man pounding on his door saying someone was trying to kill him. After the man walked away from the initial caller's home, police say dispatch received a call stating that a man had smashed out the front window of another residence on the block and went inside.

Officers located the suspect armed with a knife, according to the police department, and attempted to speak with him. At this time, police say another window broke, and officers heard a sound they say could have been gunfire; this has not yet been confirmed.

SWAT personnel responded to the scene, and after roughly 40 minutes of commands, police say the suspect exited the home still armed with a knife and ignoring officers' orders.

Police say they ultimately used a Taser and less than lethal munitions to take the man into custody. The suspect was treated on scene by the West Allis Fire Department and taken to an area hospital for medical clearance.

An investigation is ongoing.
