Police in Tamamura, Gunma Prefecture, said Monday they have arrested a 32-year-old woman over the death of her 3-year-old son.
According to police, Yusuke Tamura died from sustained head injuries after being violently thrown into a wall by his mother at their home. TBS quoted police as saying the incident occurred at around 5 p.m. on Aug 29.
Police said the mother, Akiko Tamura, turned herself in at a police station at around 2:30 a.m. on Saturday and said the body of her son was in her car.
An autopsy, conducted on Sunday, showed that the boy may have been subject to physical abuse on a regular basis as there were bruises all over his body, TBS reported.
Police quoted the boy's mother, Akiko Tamura, as saying she threw her child against the wall after getting angry at him for not listening to her.
Tamura's husband and the couple's three other children were not home over the weekend, police said.
Police said Tamura was arrested in 2010 over the death of her second oldest son, but she received a suspended sentence.© Japan Today
