He said the five were arrested for disturbing public peace and order during the protest held outside the Bosnian state parliament building and the Council of Ministers headquarters in Sarajevo.
After the protesters unblocked the government and parliament buildings early on Friday morning, the situation is peaceful.
Nearly two thousands protesters who blockaded parliament in the Bosnian capital Sarajevo on Thursday, venting anger over a political dispute that has left the country unable to register newborn babies for months, removed the blockade early on Friday morning and all people trapped in the building were evacuated under police protection.
After High Representative Valentin Inzko acted as a mediator, the protesters, mainly students and young parents with babies who surrounded the parliament, agreed to have state officials and clerks and some 350 foreign nationals released from the building.
Inzko promised them that the issue of the 13-digit identification numbers assigned to every citizen would be resolve soon and that the international community, namely the Peace Implementation Council, would also invest efforts to find a solution to this problem. The protest was organised over the failure of lawmakers from the country's rival Serb, Croat and Muslim communities to agree on how to draw up the districts that determine the 13-digit identification numbers, meaning newborns cannot be issued with passports.
The nongovernmental organisation Student Parliament of the Sarajevo University said it would organise a new protest on Friday afternoon at one of the city squares. The student NGO said Thursday's protest was only the beginning of the fight for changes.
It is yet unknown who is behind Thursday's protest.
Protests motivated by the blockade of state institutions in Sarajevo over the personal identification number issue were also organised in the southern Bosnia and Herzegovina town of Mostar on Friday.
