Crime map reveals the city's black spots
Triads, troubled youth, vulnerable old people, drugs and prostitutes are rife in Yuen Long, where serious crime is at its highest in Hong Kong.
The area sits on the periphery of the city - both physically and socially - and has the highest rates of serious crime.
This is one of the many findings from a detailed crime map, drawn from police figures obtained by the Sunday Morning Post.
Citywide, police recorded 81,125 crimes last year, up 4.7 per cent on 2005.
Mong Kok, one of the most densely populated places on Earth, recorded the most offences last year - 6,131, just ahead of Yuen Long's 5,989.
A breakdown of the crimes shows that drug-related offences pushed Mong Kok into the lead but Yuen Long had the most instances of rape, wounding and stealing. Next was Sham Shui Po with 5,703, just ahead of Kwun Tong with 5,602 and Wan Chai's 5,136.
