Mainland overstayers freed from Victoria Prison last night said they considered yesterday's court decision a small victory and pledged to fight on for residency rights. One woman, detained since Tuesday, said: 'I have more confidence than before I was arrested. I definitely have hope the final court decision will be in our favour, but I'm still very worried.' The 25-year-old from Fujian, who has been applying to live with her parents in the territory since she was five, said she was upset the Government had delayed releasing them until more than seven hours after the court decision. All mainland immigrants arrested for overstaying their visit permits were released after the Government lost its battle to keep them behind bars. The released migrants must report to police every two weeks. Elderly parents stood outside the prison for hours waiting to take their children home. 'My dad is 72 years old and has trouble with his leg. Why did the Government have to arrest us in the first place? They should have waited until the end of the appeal,' a woman said. She said 15 arrested migrants went on a hunger strike on Wednesday, missing breakfast and lunch. They resumed eating only on learning that the Legal Aid Department was helping them to appeal for their release. Another woman said she was pressured by officials to sign a letter agreeing to return to the mainland. 'They said 'If you don't sign, we'll put you in jail'. I said 'OK'. They said 'We'll put you in jail for eight to 10 years', but I refused to sign,' she said. Her father said: 'This is a good sign. I'm determined to fight for this to the end.' Another parent said he had told his son not to sign any form to agree to go back to China. 'I said 'Once you go back, there's no hope of coming back ever again'.' Immigration Department officials denied that they pressured anyone into returning to the mainland. Since Tuesday, 56 people have voluntarily returned to the mainland, including seven yesterday.
