MUSKEGO, Wis. (CBS 58) -- Police say a Taco Bell employee in Muskego was arrested Monday, March 2, after allegedly firing a gun during an altercation with customers outside the fast-food restaurant. 

Officers responded to the Janesville Road location around 1:10 p.m. after officials say a physical fight began between two patrons and several staff members inside the business. 

Shortly after multiple people involved stepped outside, police say an employee fired several rounds from a handgun. 

No one was struck by the gunfire; however, officials say one person was taken to a local hospital with non-life-threatening injuries related to the fight.  

Muskego police say the customers involved left the scene before their arrival.

A charge of first degree recklessly endangering safety will be referred to the Waukesha County Sheriff's Department against the employee who fired the weapon. 

An investigation remains ongoing.
