A 17-year-old high school student was arrested Tuesday on suspicion of killing an elderly woman Monday in her house in Toyokawa, Aichi Prefecture, police said.
The teenager, a third-year student at a private high school, surrendered Tuesday afternoon shortly after police obtained an arrest warrant for him on suspicion of killing Kiyo Tsutsui, 65.
The teenager had not been seen since Monday evening but appeared unaccompanied Tuesday at a police box in front of JR Nagoya Station at around 5:30 p.m., police said. He was later transferred to the police station in charge of the case.
Hiroshi Tsutsui, 67, returned home from a walk at around 6:10 p.m. Monday to find the front door locked. An unidentified male subsequently rushed out from another entrance to the home.
