HONOLULU (KHON) – City officials in Honolulu are sharing a safety message with the public: Stay out of the city’s storm drain system. This comes after a homeowner claims two strangers suddenly popped up out of a manhole on his property this week. It is not a typical complaint to the city: A homeowner in Kaimuki said he was in his garage around 8:30 a.m. Tuesday when he started to hear noises coming from his backyard.
