Police in Kiryu, Gunma Prefecture, have arrested a 40-year-old man for abusing his 6-year-old son.
According to police, Shinobu Endo, who is a truck driver, grabbed his son by the hair and slammed his face into a wall on June 7, Sankei Shimbun reported Saturday.
Sources say the boy will be in hospital for at least two weeks after suffering several cranial injuries.
Endo was quoted by police as saying his son wouldn't listen to him, but denied pushing the boy hard enough into the wall to cause any real harm.
The boy's teacher noticed his injuries and alerted child welfare authorities.
Endo lives with his 31-year-old wife and four children. None of the other children showed signs of abuse, police said.© Japan Today
