SBU (now known as SBDIV) was formed in 1979 to help stem the influx of illegal immigrants. In 1990s it worked closely with the Anti-smuggling Task Force to tackle the "Daai Feis", high-powered vessels used by smuggling syndicates. Today, SBDIV is widely respected by local and overseas law enforcement agencies on account of its specialised skills, tactics and resources to perform its core role of high-speed pursuit and interception.

Speaking at a ceremony, Mr Tsang pointed out that SBDIV had achieved significant results in enforcement over the years, which had contributed positively to the security and law and order situation of Hong Kong waters.

He praised SBDIV officers for their professionalism, perseverance and courage and encouraged them to keep up their efforts and carry out their duties in a safe and effective manner.

Mr Tsang, proud of the achievements of SBDIV, added that the division would continue the development of its craft, training, tactics and equipment to meet the challenges ahead.

SBDIV, with strength of over 130, currently operates a fleet of eight Fast Pursuit Craft and five High Speed Interceptors, in support of other units of Marine Region, to primarily perform the highly specialised and potentially hazardous task of high-speed pursuit and interception.

From January 2006 to October this year, SBDIV seized some HK$320 million worth of contraband along with 82 vessels of assorted sizes and 27 assorted vehicles, and between March 2006 and October this year, officers of the division arrested a total of 1,045 illegal immigrants.
