An off-duty Honolulu police officer was arrested Sunday afternoon for allegedly accidentally shooting and wounding a South King Street female bar employee in the stomach early Friday morning.

Sgt. Anson Kimura, a 25-year veteran officer, is assigned to District 1, which includes Chinatown. He turned himself in at the main police station and was booked on suspicion of second-degree assault and released pending further investigation.

No formal charges have been filed.

Kimura also is being investigated  by HPD’s Professional Standards Office, whose findings could range from a written reprimand to expulsion from the force, said Deputy Police Chief Dave Kajihiro at a Friday news conference.

The officer’s police powers have been restricted, Kajihiro said.

Kajihiro said police are investigating whether Kimura was drinking Friday morning when the woman was shot.

Kajihiro said a 40-year-old employee of King’s Sports Bar on South King Street was shot in the stomach just before 2 a.m. when a handgun was “accidentally discharged.”
