A high-school teacher has been accused of faxing death threats to one of his pupils from his previous school in Morioka, northern Japan.
Police said he targeted the girl because her mother had complained about his teaching methods.
The 44-year-old teacher who cannot be named for legal reasons, allegedly sent seven death threats to an unnamed girl from February to April last year.
The teacher denies the charges, but investigators said that telephone records trace the faxes to his home. The teacher was transferred away from the girl’s school in April last year after she reported the faxes to the school and the police.
