Police served an arrest warrant Thursday on a 64-year-old man in connection with the shooting of a subway station employee during a robbery at Tokyo's Shibuya station last week.
Tokuhisa Kumagai was initially arrested Saturday for alleged violation of the firearms control law after he turned himself in along with a .38 caliber revolver at the Metropolitan Police Department and admitted he perpetrated the Shibuya Metro Station shooting.
Police suspect Kumagai shot and wounded Shigeo Nishioka, 32, in an underground passage at the station during the June 23 morning rush hour and made off with a paper bag of the victim's containing a toilet kit, believing the package contained money.
Investigation sources said Kumagai has given specific testimony on the incident to interrogators.
