A second arrest warrant was served Wednesday for an American man already in custody in connection with a human head and other body parts discovered in Osaka and Kyoto prefectures, police said.

The man, Yevgeniy Vasilievich Bayraktar, was re-arrested on suspicion of abandoning the body parts identified as those of a 27-year-old woman from Hyogo Prefecture.

The Hyogo Prefectural Police, who served the new arrest warrant, identified the victim as Saki Kondo, who Bayraktar was seen with prior to her going missing.
