A man under arrest for allegedly kidnapping a 12-year-old girl in Osaka and confining her in his Tochigi home has told police he "did the right thing," investigative sources said Monday.

The suspect, Hitoshi Ito, 35, became acquainted with the girl via social media around Nov. 10. and they decided to meet in a park in Osaka four or five days later.

After being missing since Nov. 17 from her home in Osaka, she showed up Saturday at a police box in Oyama, Tochigi Prefecture, more than 400 kilometers away. Ito was arrested by Osaka Prefectural Police later that day.
