Vantaa|leftThe National Bureau of Investigation (NBI) was established on 30 December 1954 upon ratification of Act 510/1954 and became operational in 1955 by merging the
Uusimaa Province Crime Police Centre () and the Crime Research Centre (). Previously, the Crime Police Centre had been handling nationwide investigations while the Crime Research Centre was in charge of intelligence and forensic analyses. Kosti Vasa was appointed NBI's first Director and served as such until retiring in 1965. In the wake of the
2004 Indian Ocean earthquake and tsunami, NBI's Finnish Disaster Victim Identification Team (DVI) was dispatched to identify Finnish victims in Thailand. 173 out of the 178 Finns missing in Thailand were eventually identified. In April 2013, NBI came under public pressure after it was revealed that the Bureau had collected mostly indirectly connected information of suspicious persons with possible links to organized crime into a secret intelligence database. Russian president
Vladimir Putin was one of the persons recorded after his interaction with the motorcycle club
Night Wolves. According to prosecutors, the database was lacking proper controls and vulnerable to unauthorized use. Reporters speculated in the media that having a record in the database could possibly cause financial losses and social exclusion for registered persons—who had no means to verify or be aware if they had been recorded. By April 2016, 97.3% of the nearly 50 000 entries had been determined legal and the rest deleted. Similarly, a new unit targeting cyber crime was established at the Bureau's headquarters in April 2015 with a preliminarily number of 45 staff. The unit's chief named concentrated
cyber attacks as Finland's greatest threat at the time. In March 2015, the Bureau opened its first official
Twitter account and in August 2015, opened its doors for the first time to the public and allowed visitors to see contents of the Bureau's Crime Museum as well as art forgeries kept inside its headquarters. NBI was in charge of investigating the
Turku stabbing of August 2017; considered Finland's first suspected terrorist attack since the end of World War II. == Mandate and organization ==
