South China Morning Post Three Hong Kong teenagers arrested over an alleged terrorist plot to bomb streets, courts and transport networks have been charged under the national security law and remanded in custody. The three secondary school boys were charged with conspiracy to commit terrorist activities when they appeared at West Kowloon Court on Wednesday evening. They are Ho Yu-wang, 17, Alexander Au, 19, and a 15-year-old who cannot be identified. The two older defendants both study at a government school in Kwun Tong, while the third is a student at an institution in Tseung Kwan O. The charge carries a maximum penalty of a life sentence, but local laws governing juvenile proceedings stipulate that defendants under the age of 16 cannot be sent to jail unless no alternative sentencing options exist.
