Thai authorities have confirmed the death of another Hong Kong foreign resident missing since December's tsunami, bringing Hong Kong's death toll to 23.

The Security Bureau said 17 Hong Kong residents remain unlocated, and all are reported to have been in Thailand when the tsunami struck. The Government will pursue these cases and provide assistance to residents and their families where necessary.

Police have contacted relatives of missing Hong Kong residents to collect DNA samples for analysis on a voluntary basis. Analysed DNA information and fingerprint records have been sent to Thailand for identification.
