Authorities said a gun was fired during an altercation between a Walworth County sheriff's deputy and a patient prisoner at an Elkhorn hospital.

Aurora Healthcare spokesman Adam Beeson said the incident in a room at Lakeland Hospital Monday night was isolated. He says it was not an active shooter scenario. Beeson would not say if the patient was struck, citing privacy concerns.

WISN-TV reported  the Waukesha County Sheriff's Department is investigating the incident at the request of the Walworth County sheriff.
