A 20-year-old Mililani man who allegedly threatened a group of men at gunpoint in a Pearl City park last week is behind bars, but another gunman is still at large, police said.

Police said the suspect and another man drove up to a group of eight men, ages 18-20, who were hanging out at an unidentified Pearl City park at 9:30 p.m. Thursday. The two suspects pulled out guns. The 20-year-old man pulled threatened one of the men with a gun, while his accomplice pointed his gun at the other men, police said.

The 20-year-old suspect then used his gun to smash the windshield of one man’s car with four people inside, police said. The other suspect hit the side-view mirror of another car with his gun, police said.

Police identified the 20-year-old man through a photo lineup and arrested him yesterday afternoon at the Pearl City police station on 14 charges, including terroristic threatening, firearms and drug offenses.
