A 23-year-old man has been charged with carjacking a 65-year-old man at a gas station in Kailua-Kona.

Prosecutors charged Derek I. Hanato of Kailua-Kona today with unauthorized use of a propelled vehicle, accidents involving bodily injury, driving under the influence of an intoxicant, second-degree robbery, inattention to driving, second-degree theft, second-degree assault and first-degree criminal property damage.

His preliminary hearing is scheduled for Wednesday at Kona District Court. Hanato remains in custody in lieu of $83,000 bail.

Police said the victim, of Kailua-Kona, stopped at a gas station on Kuakini Highway at about 11:47 a.m. Sunday. He stepped out of his 2012 Honda Accord with the engine still running to clean his windshield when a man later identified as Hanato approached him, knocked him down, and took his vehicle, police said.

The victim was injured in the assault.

Hanato then sped off northbound on the highway, ran a red light and broadsided an SUV on Palani Road, injuring a passenger in the SUV.

Hanato fled the scene on foot. Police said a good Samaritan followed and detained him until police arrived and arrested Hanato.

He has a criminal record of felony burglary and theft, misdemeanor theft and petty misdemeanor criminal trespassing.
