A man in his 30s was apparently drunk when he was struck by a pickup truck early Sunday morning in the Ala Moana area.

Police said alcohol was a factor on the part of the man, who was lying in the roadway when he was hit at 3:55 a.m. at Kona Street, near Piikoi Street.

Police said a 31-year-old man got into his parked Ford F-150, put it into drive and struck the man lying in front of his truck.

The injured man was taken to a hospital in serious condition, police said.

Speed and alcohol were not factors on the part of the pickup truck driver.

The investigation is ongoing, police said.
