A 35-year-old man was arrested Thursday after the exhumation of a body, confirmed later to be that of a missing 19-year-old female university student, east of Tokyo.

The Metropolitan Police Department arrested Koichi Hirose on suspicion of dumping the body, which was found earlier in the day on farmland in Kamisu, Ibaraki Prefecture, based on information provided by the suspect. The body was located 12 km from his apartment.

Hirose is said to have told police that he killed the woman after she screamed and then dumped her body. He also told police he first met the victim online before she disappeared last November.
