OSAKA -- The junior high school girl, who asked to be referred to only as "Son," appeared on the verge of tears when she recalled what happened.

"It was a morning in early October. I put on my 'chongiri' (traditional Korean dress), got on my bicycle and headed for school. As I was riding along, something struck me in the back.

"I turned around and saw a man drop some stones and run away. It took me a minute to realize that he was throwing them at me," she said.
