Police on Wednesday arrested one of the two suspects in last week's abduction and confinement of a 7-year-old girl in Kuroiso, Tochigi Prefecture.

Arrested was 22-year-old Ryuichi Fujita, who police believe to be the main culprit in the case. His friend and alleged accomplice, Kunihiko Tanaka, 21, remains on a nationwide wanted list. Both are residents of Kuroiso.

Tochigi police received a call around midnight Tuesday from Fujita's mother, who told them her son would soon turn himself in. Investigators, however, went to Fujita's home and asked him to accompany them to the station, according to police.

He was arrested at 1:44 a.m. Wednesday at the Kuroiso police station on suspicion of abducting a minor.
