Hong Kong authorities have confirmed through a Hong Kong baby DNA test that an unmarried couple arrested in a child neglect investigation are the biological parents of an undocumented infant known as Danny.
Police sources said on Thursday that Tsang Wai-bong and Kwan Pui-sin were identified as the parents following DNA testing, according to reporting from local media.
The case involves a two-month-old baby who was reportedly born at home and not officially registered with the Immigration Department. Authorities said the child’s legal status was unclear because the parents initially refused to submit DNA evidence confirming their relationship.
The confirmation now provides investigators with a key piece of evidence as the broader neglect investigation continues.
Police arrested the couple earlier on suspicion of child neglect after concerns were raised about the welfare and legal documentation of the infant. Officials have not released further details about the conditions in which the child was being cared for.
The case has drawn attention in Hong Kong due to concerns over unregistered births and the legal protections available for children born outside formal hospital systems.
Authorities said the DNA results confirm the biological link between the couple and the child, strengthening the factual basis of the ongoing investigation.
The infant, known as Danny in local reporting, was born outside of official registration procedures, which meant he was not immediately recorded in government population records.
Under Hong Kong regulations, parents are required to register births with the Immigration Department within a set period. Failure to do so can result in legal consequences and complicate access to healthcare, identity documents, and social services.
Officials are now expected to continue examining whether additional legal violations occurred beyond failure to register the birth, including potential neglect-related offences.
The case also highlights broader concerns among social welfare experts about undocumented births and the challenges faced by authorities in ensuring child protection in such situations.
Authorities have not confirmed whether the child has been placed under protective care or with social services while the investigation is ongoing.
Police said inquiries are continuing and further updates will be provided as the case develops.
The Hong Kong baby DNA test result is considered a critical development in establishing the legal relationship between the suspects and the infant, which is central to determining potential charges in the case.
