Law and order in Thimphu and in the country as a whole are the responsibility of the Royal Bhutan Police (RBP), a national police branch of the armed forces, established in Thimphu in September 1965 when 555 personnel were reassigned from the Royal Bhutan Army. The organization is responsible for law and order, traffic control, and crime prevention. In 1988, a fingerprint bureau was established in Thimphu, for which a female second lieutenant received specialized training. Bhutan became a member of Interpol on 19 September 2005; since then, Interpol has maintained a National Central Bureau at RBP headquarters in Thimphu.
