A grand jury has decided against indicting a Honolulu police sergeant who was investigated for domestic violence because of an incident with his girlfriend that was caught by a restaurant’s surveillance cameras.

State judiciary spokeswoman Marsha Kitagawa says the grand jury met Wednesday and chose not to indict the sergeant.

The Honolulu Police Department turned the criminal case over to prosecutors, saying there wasn’t enough evidence for any charges.

The police probe was triggered when surveillance footage surfaced last month showing the sergeant punching his girlfriend at a Waipahu restaurant. The woman reportedly claimed it was horseplay.

Police spokeswoman Teresa Bell says an administrative review of the officer continues. He remains without any police powers. The department is also investigating the responding officers who didn’t file a report about the incident.
