A 44-year-old Mililani man was arrested after he allegedly shot at his girlfriend after discovering her asleep in bed with another man at the second man’s house half a mile away from his own on Wednesday morning.

Police said the suspect removed several louvers, reached into the bedroom of the Kiilani Street home and pointed a handgun at the couple about 8 a.m. The second man managed to wrestle the gun away from the first man, who then fled.

The first man then returned with a shotgun and fired into the house, HPD said, but no one was injured as the couple hid behind an interior wall.

Arriving police officers arrested the suspect, of a Kauluikua Place address, at the scene about 10 a.m. He is being held pending counts of attempted murder, first-degree burglary and several firearms violations.
