Police arrested one of five suspects who allegedly impersonated police officers and robbed a 62-year-old woman in Kaneohe.

At about 9:10 p.m. Tuesday, police said the suspects entered a house and described themselves as “HPD.” The suspects — four males and one female — brandished dangerous instruments that included a loaded firearm and a bat.

Police said the suspects allegedly punched the victim during the robbery. No items were taken.

Officers arrived shortly after and arrested a 41-year-old man at Waikalualoko Loop on suspicion of first-degree robbery, impersonating a law enforcement officer and unauthorized entry in the first degree.

The four other suspects remain at large.
