Hong Kong (CNN) -- Madeleine Pulver's ordeal started last August when a man burst into her room and tied a fake bomb around her neck, and ended on Tuesday when he was sentenced to at least 10 years in jail. The Australian teenager was studying for her final year exams when 52-year-old Paul Douglas Peters broke into her suburban Sydney home and carried out what the prosecution called an act of "urban terrorism." "The terror instilled can only be described as unimaginable," Judge Peter Zahra told the District Court in Sydney during sentencing Tuesday. Pulver was in the courtroom, as were her parents, and the man who, on a Wednesday afternoon, pushed open their unlocked front door and found the 18-year-old student alone in her bedroom.
