The mother of Internet stalking victim Wu Man-ki yesterday criticised the nine-month sentence as too lenient, claiming it would not stop Tiong Teck Boon returning to terrorise the family when he was released. Speaking at her home in Ma On Shan, Chan Lai-ming, who along with her son Wu Ka-tat and her 74-year-old mother-in-law were taken hostage by Tiong in December, said: 'It doesn't stop him from entering Hong Kong and stalking us again.' It will be up to the Immigration Department, not the court, to decide whether Tiong will be barred from re-entering Hong Kong after completing his sentence. According to Ms Chan, her daughter has not made any friends via the Internet since the incident: 'She doesn't even use the computer at home nowadays,' she said. 'In fact, the computer broke down a while ago and we haven't bothered to fix it.'
