Police in Omiya, Saitama Prefecture, said Saturday they have arrested a 22-year-old woman on suspicion of murder after she beat her 21-year-old boyfriend to death at their apartment.
According to police, Momoko Yamazaki, who works at a bar, punched her boyfriend, Masafumi Kimura, with whom she lived, in the face with her fist as he slept after she returned home from shopping at around 1:10 a.m. Friday. She then went to bed.
Yamazaki told police that when she woke up at around 5 p.m. Friday, Kimura was unconscious, so she called her mother who came over at 5:45 p.m. Yamazaki's mother then called 119. Kimura was taken to hospital where he was pronounced dead.
Yamazaki was quoted by police as saying she got angry because Kimura had locked her out.© Japan Today
