Gang bust at school

Two police officers disguised themselves as students at a Tuen Mun school to investigate triad infiltration.

Police have arrested 25 people, aged between 13 and 25, in Tuen Mun since March as a result of this and other undercover work in a nine-month anti-triad operation.

Eighteen were released on bail and seven were being detained for further investigations.

Officers also infiltrated triad gangs at game centres, karaoke lounges, soccer pitches and basketball courts.
