Police have obtained an arrest warrant for the 31-year-old son of a former Colombian ambassador to Japan on suspicion of killing a 34-year-old American man in Yoyogi Park in Tokyo, sources said Monday.
Police also raided the residence of the 57-year-old former ambassador in Shibuya Ward, where the son also lived, the sources said, without identifying either person.
Police plan to place the son on an international wanted list through Interpol.
He left Japan after English conversation teacher Roberto McNeill was found murdered April 12 in a public restroom at Yoyogi Park.
Police found bloodstains believed to be those of the killer and determined from DNA tests that the former ambassador's son was involved in the murder.
