A 15-year-old high school student was arrested on Wednesday for allegedly murdering his father after the bodies of his parents were found in an apartment near Tokyo, police said.

The police, responding to a report from the father's workplace that he was unreachable, found the bodies on Tuesday evening inside the locked apartment in Sagamihara, Kanagawa Prefecture, where the three resided.
