An off-duty Andover police officer was assaulted early Saturday morning at the IHOP located in the 11000 block of East Kellogg.
The officer was eating in the restaurant when staff asked him to help break up a fight.
He walked one of the people fighting out to his vehicle. The suspect then pulled out a pocket knife, threatened to kill the officer, and then locked himself in the car.
Wichita police took the suspect into custody.
