Montenegrin police have detained several relatives of Bosnian Serb war crimes suspect Radovan Karadzic, as part of an ongoing push to track down the fugitive.
Karadzic's brother told reporters that police in the northwestern town of Niksic had taken the fugitive's sister and her husband into custody Saturday for questioning, before releasing them hours later.
Bosnian Serb wartime leader Karadzic and his former top military commander, Ratko Mladic, have been indicted by the United Nations war crimes tribunal in The Hague on genocide charges linked to the 1995 Srebrenica massacre of up to eight thousand Muslim men and boys.
Authorities say Karadzic - a fugitive since 1997 - is hiding in the Serb-run part of Bosnia-Herzegovina, or in adjacent Montenegro or Serbia. Mladic is thought to be harbored by hardliners in Serbia.
