Law enforcement in Bosnia and Herzegovina is the responsibility of an EU-sponsored Bosnia police force to which the role of maintaining security in the region was handed over from the United Nations's 18,000 International Police Task Force. Since 1 January 2003 the European Union Police Mission in Bosnia and Herzegovina (EUPM) was tasked with creating a new stable police force for Bosnia and Herzegovina, however this has been met with limited success. Outlined by the EUPM, the new Bosnian Police force would have the responsibility of fighting migrant smuggling, customs evasions as well as dealing with the tensions raised by the return of refugees.
