A 20-year-old Haiku man was arrested late Sunday for a hit-and-run after he allegedly injured two moped riders in Kaneohe.

Traffic investigators said the suspect was driving a gray 1998 Toyota on Kahekili Highway near Kahuhipa Street at around 8:30 p.m. when he maneuvered around a stalled vehicle and ran into a red moped carrying two people.

The 45-year-old moped driver was taken to Queen’s Medical Center in critical condition. His passenger, a 37-year-old woman, also was taken to Queen’s Medical Center in serious condition.

Both moped riders were not wearing helmets and suffered head and internal injuries.

The 20-year-old driver was not injured.

The driver fled the scene, but police said his girlfriend convinced him to turn himself in.

He was later arrested at his Haiku home for failure to render aid.
