About the Section

An Amendment Bill to three of the security-related ordinances, namely the Dangerous Drugs, Independent Commission Against Corruption and Police Force (Amendment) Bill 2000 was introduced to the Legislative Council in the beginning of the year 2000. After some twenty meetings in which members of the Council deliberated in detail its contents, the Bill was finally passed as Ordinance in June 2000. In the Dangerous Drugs, Independent Commission Against Corruption and Police Force (Amendment) Ordinance 2000, provisions were made for the setting up and maintaining by the Government Laboratory, on behalf of the Commissioner of Police, a database storing DNA information of persons convicted of a serious arrestable offence.

 

 

 


Responsibilities

The DNA Database Section was set up subsequently in October 2000 in the Government Laboratory. Its main responsibilities are to perform DNA analysis on samples from persons convicted of a serious arrestable offence, those suspected of having committed a criminal offence and volunteers, set up in computerized form a DNA database and administer and maintain that database.

A DNA database on convicted persons is only useful for crime investigation if the information could be compared against DNA information of unsolved cases. Whilst DNA information of unsolved cases will be generated by the Biochemical Sciences Sections, both the DNA Database Section and the Biochemical Sciences Sections will have to use the same techniques for information to be compatible and comparable.
