A Santa Rosa police officer was accidentally shot during a practice session at a shooting range in West Marin, officials said.

The incident occurred shortly before 4 p.m. at the Circle S Ranch and Shooting Range at 1740 Tomales-Petaluma Road. The range is sometimes used for training and practice by various law enforcement agencies.

An officer was clearing a round from a .40-caliber gun when the gun went off, sending a bullet into a concrete table. The bullet broke apart, and fragments struck a different officer in her leg, hand and face, said Marin County sheriff’s Sgt. Debra Barry.

The injuries were described as minor. The officer was airlifted to Santa Rosa Memorial Hospital for treatment, said Marin County fire Capt. Rick Wonneberger.

No further investigation is planned, Barry said. The officer whose gun discharged also works for the Santa Rosa Police Department.

The proprietors of the shooting range did not return a call seeking comment.

The range, which sits on a 196-acre ranch two miles west of Two Rock, has been in use for nearly 40 years. The range itself consists of four shooting lanes on a 19-acre tract, according to county records.

In March 2009, an agent with the Internal Revenue Service was wounded when his gun accidentally discharged and sent a bullet into his leg during a qualification session.
