Jakarta, Indonesia (CNN) -- A 14-year-old Australian boy accused of marijuana possession could face jail time on the resort island of Bali. With his face covered in a black mask, the teenager was mobbed by the media as he entered a local court complex for the first day of his trial Tuesday. Earlier, prosecutor Gusti Gede Putu Atmaja said the judge would not wear his usual robe to try to minimize stress on the boy. The trial is closed to the public. The Australian teen -- whose name has not been publicly released -- faces three charges under Indonesia's stringent narcotics laws.
