Police Chief Kevin Warren, of North Ogden, Utah, unintentionally shot himself Thursday during a training exercise at the department's shooting range.
"He was doing some drills required of him that involved reaching across his body to get his gun," said a police spokesperson. "Somehow, his finger hit the trigger."
Warren's .40-caliber handgun discharged and the bullet hit his right forearm. He was taken to the local hospital where he was treated and released.
The training exercise was described as a simulation of scenarios officers are likely to encounter in the line of duty. Two certified firearms instructors were supervising the range at the time.
Warren has 33 years of law enforcement experience.
"You know, if you drive a car for 30 years there's a good chance you will get in an accident," the police spokesperson added. "Same here, this can happen to the best of them."
