Twenty-two-year-old twin brothers were arrested following a brawl in the Kapiolani Boulevard area early Thursday morning, police said.

Officers responding to a large fight at a Kapiolani bar at 3:32 a.m. managed to disperse most of the crowd, but one man refused to leave and continued to challenge others to fight, police said.

An officer attempting to stop the man as he was attempting to assault another man used pepper spray to stop the suspect, police said. As the officer did so, the suspect’s twin brother grabbed and shoved the officer.

The first brother was arrested for disorderly conduct and the other for harassment, police said.
