A 25-year-old man was served a fresh arrest warrant Saturday on charges of murder after being arrested last month for allegedly disposing of the bodies of a Tokyo couple in Tochigi Prefecture.
A total of six people have been arrested over the incident, but the man, Ryoken Hirayama, is the first to be charged with murder.
A joint investigation team of Tokyo's Metropolitan Police Department and the Tochigi Prefectural Police believes that Hirayama, was asked by another man who issued instructions to kill the couple, and that he prepared the car used in the plot and recruited two other men to carry out the murders.
