The unnamed officer was hunting in the North Cumberland Wildlife Management Area in Campbell County when he shot the two other hunters by mistake, The Associated Press reported.
The Tennessee Bureau of Investigation (TBI) is looking into the shooting.
The incident took place before 10 a.m. Sunday, local outlet WKRN reported. One of the hunters, whose name were withheld, was transported to a medical center for examination while the other victim was able to drive himself.
"One victim was transported and the other drove himself to [University of Tennessee] Medical Center for examination," officials said in a press release shared with WKRN. "Both victims have been released and the incident is under investigation by the Tennessee Bureau of Investigation."
A spokesperson for the TBI confirmed the investigation is ongoing to Fox News.
"At the request of the Tennessee Wildlife Resources Agency and 8th District Attorney General Jared Effler, TBI Special agents are investigating the circumstances leading to a shooting incident involving an off-duty TWRA wildlife officer that occurred Sunday morning in Campbell County. Two people were injured during the incident. Both received treatment at a local hospital and have since been released. The investigation remains active and ongoing."
According to an update on the TWRA’s website, turkey hunting season is open for the regular season and “public lands controlled by the TWRA will remain open” during the coronavirus pandemic.
