On 27 September 2004, it was reported that British spies across the Balkans, including an SIS officer in Belgrade and another spy in Sarajevo, were moved or forced to withdraw after they were publicly identified in a number of media reports planted by disgruntled local intelligence services – particularly in Croatia and Serbia. A third individual was branded a British spy in the Balkans and left the office of the High Representative in Bosnia, whilst a further two British intelligence officers working in Zagreb, remained in place despite their cover being blown in the local press. The exposure of the agents across the three capitals markedly undermined the British intelligence operations in the area, including SIS efforts to capture The Hague's most wanted men, which riled many local intelligence agencies in the Balkans, some of which are suspected of continuing ties to alleged war criminals. They were riled due to MI6 operating "not so much a spy network as a network of influence within Balkan security services and the media," said the director of the International Crisis Group in Serbia and Bosnia, which caused some of them to be "upset". In Serbia, the SIS station chief was forced to leave his post in August 2004 after a campaign against him led by the country's DB intelligence agency, where his work investigating the 2003 assassination of the reformist prime minister Zoran Djindjic won him few friends.
