The principal of a junior high school in Hiroshima Prefecture apologized Wednesday after a boy killed himself over an incident stemming from a clerical mistake.

The school last year refused to support the graduating student's high school entrance application because its records wrongly showed that he had a petty theft record.

The 15-year-old killed himself on Dec. 8 after the school informed his parents that it would not issue a personal recommendation to his chosen high school because his student file stated he had been caught shoplifting during his first year at the school.
