HONOLULU (AP) -- Police in Hawaii say a man dressed in hospital garb threw a toddler 30 feet from a pedestrian overpass onto a major highway Thursday.
The boy was later pronounced dead. Authorities say one or two vehicles may have hit the two year-old, but it's not clear exactly what killed him.
A 23-year-old man is under arrest after witnesses saw him throwing something, followed him and called police.
Officers are contacting day-care centers and other area facilities to find out where the child came from. They say there had been no reports of a missing child.
Police temporarily closed the westbound lanes of the H-1 freeway, a major route into downtown Honolulu.
