Following an invitation by the Bosnian authorities, the EU decided to establish a follow-on police mission with a modified mandate and size. EUPM II lasted for two years (from 1 January 2006 until 31 December 2007). It monitored, advised and inspected BiH police forces according to three main pillars, i.e. support to the police reform process, strengthening of police accountability and supporting the fight against organised crime.
