Hong Kong authorities have confirmed that an unmarried couple arrested on suspicion of child neglect are the biological parents of undocumented infant Danny. A police source told the South China Morning Post on Thursday that Tsang Wai-bong and Kwan Pui-sin were the parents of the two-month-old, citing DNA test results. Danny was born to the unmarried couple at home in Hong Kong and was not registered with the Immigration Department, as his parents declined to submit a DNA test report to confirm.
