Reciprocal Arrests?

Last week, five Serbs were arrested for transporting election material into Kosovo by the KPS.  A few days ago, Serbian police allegedly crossed the boundary into Kosovo and arrested two KPS officers who were allegedly 130 meters within Kosovo (I say allegedly because the investigation into what really happened is ongoing and the political rhetoric is high.)  However, Serbia released the KPS officers to EULEX on Monday, 02 April.
