TOKYO (AP) _ A Buddhist monk who headed a reform school was arrested on suspicion of beating a 15-year-old boy to death with a baseball bat, police said today.

Rinzo Kagawa, 41, was arrested Wednesday after student Mikinori Tsuchida died of trauma induced by severe beating, according to police official Shosuke Hikima.

Hikima said the monk ordered five other pupils to help him beat the boy with metal baseball bats. Kagawa told police he punished Tsuchida for assaulting his mother.
