The second of three suspects has been charged in connection with a home invasion robbery in Punchbowl that police said involved suspects impersonating police officers.

Kahoku Tampos, 30, was charged Saturday with first-degree robbery, kidnapping, burglary, impersonating a law enforcement officer and fourth-degree sexual assault. He was being held in lieu of $200,000 bail.

Tampos was arrested Saturday afternoon at Wal-Mart, 700 Keeaumoku St.

The first suspect arrested, 25-year-old Anthony Riley, was charged Friday with seven crimes, including robbery, kidnapping and burglary, in connection with the early morning incident on May 17.

Riley was arrested Wednesday at Kapolei Marketplace and was being held in lieu of $200,000 bail.

Police said three assailants wore shirts bearing the letters SHOPO, for the State of Hawaii Organization of Police Officers (the police union), and entered the family home in a walk-up condominium on Kamamalu Avenue after a 47-year-old woman answered the doorbell. The woman told police she opened the door because someone outside said it was the police.

The suspects bound four victims in the home, including a 23-year-old man, his parents and a friend of the man’s sister, and took cash and belongings.

Police said one suspect fondled the 47-year-old woman before leaving the scene.
