A British tribunal has ruled that a former member of the UN police force in Bosnia was unfairly fired after she reported to her superiors that colleagues in the police force used women and children as sex slaves in connivance with Balkan traffickers. It was at least the third scandal this year involving international aid workers and vulnerable local populations. The UN officially has not commented on the latest case, in which the whistleblower, Kathryn Bolkovac, an American citizen living in the Netherlands, charged she was fired in 2000 for sending e-mails to her employer, the U.S. recruitment agency DynCorp, stating that other UN police officers from several countries were linked with prostitution rings. Bolkovac was posted to Sarajevo in 1999 to investigate sex trafficking but soon began filing reports that UN officials and international aid workers themselves were involved in it. She said UN workers frequented bars where girls as young as 15 were forced to dance naked on tables and engage in sexual acts with clients. UN peacekeepers stood by while girls who refused to take part in sex acts were beaten and raped by pimps. One police officer paid $1,000 for a girl he kept captive in his apartment. Earlier this year, a joint report by Save the Children and the Office of the UN High Commissioner for Refugees said that about 70 workers from aid organizations and UN agencies were suspected of extorting sexual favors from children and young women among refugees in Guinea, Sierra Leone and Liberia in exchange for food.
