The Chiba prefectural police called a doctor to Gyotoku police station in Chiba where Ichihashi, 22, is being held to administer nutritional supplements to him, fearing that he may become ill if he continues to eat nothing, the sources said.
They said Ichihashi has remained silent about the allegation that he abandoned Hawker's body on the balcony of his apartment in Ichikawa, Chiba Prefecture, in March 2007 -- the technical grounds on which he was arrested.
Ichihashi was seized Nov. 10 at Osaka port in western Japan by police officers who were tipped off that a man resembling the photo of Ichihashi on a wanted poster was waiting at a ferry terminal.
