An international school principal arrested Sept. 28 on suspicion of attempting to smuggle marijuana into the country faces further punishment following her suspension, an official of the International School of the Sacred Heart in Tokyo said Friday.

"What (Kindergarten and Junior School Principal Shirley Lane) allegedly did is very serious," said business manager Naruhiko Soga. "Considering her important position as a principal, the impact is not small. We are discussing punishing her severely.

"We only know what has been reported in the media, so we will decide on the punishment after we learn whether she will be indicted or not."
