Appleton Police say one person is dead after an officer-involved shooting at a bar in downtown Appleton.
Just after 1:30 a.m., officers working foot patrol in the 500 block of West College Avenue were alerted to a shooting inside Jack's Apple Pub.
"It was a disturbance between two males in the bar. One of the males fired a gun and fired at least one round at the other male," said Chief Thomas.
When officers arrived they could see people leaving the bar.
Officers then took up positions at the front and side doors of the pub.
According to police, Lieutenant Jay Steinke then entered the South State Street side of the business encountered a subject with a gun.
"The Lieutenant fired his weapon at the suspect before seeking cover outside of the door way," said Police Chief Todd Thomas.
More officers then entered the building to render aid and to provide safety to anyone left in the building.
Police tell NBC26 the suspect was taken to a local hospital but later died.
"Lieutenant Steinke encountered an active shooter situation and used a firearm to stop a threat in an extremely dynamic situation. This is a tragic incident that all of us wish never occurred," said Chief Thomas.
Two people inside the pub were taken to local hospitals with non-life threatening injuries.
Preliminary investigation indicates this was an isolated incident and there is no ongoing threat to the community.
No officers were injured during the call.
Appleton Police say they have contacted Green Bay Police to help with the investigation.
Anyone with information are asked to call Appleton Police at (920) 832-5500.
