Neighbors in the apartment complex where a 23-year-old man suspected of abducting a Saitama girl lived said on Monday they were mystified he could have held the girl inside.

Kabu Terauchi, who was taken into custody the same day, moved into the apartment in Tokyo's Nakano Ward in February from Chiba, investigation sources said. The girl from Asaka, Saitama Prefecture, now 15, had been missing since March 10, 2014.

Police said Terauchi's apartment was in an area about 300 meters from Higashi-Nakano Station, where the girl was found and taken into protective custody Sunday.
