A file photo from June 27, 2002 shows Svetlana 'Ceca' Roznjatovic, one of the most popular singers in Serbia, talking to journalists in Banja Luka. Serbian police hunting for the killers of Prime Minister Zoran Djindjic on Monday raided the Belgrade home of feared warlord Arkan's young widow. B92 radio, quoting sources close to the investigation, said police had detained Raznatovic 'because of her close links' to a prime suspect, alleged Serbian gangster boss Milorad Lukovic, or Legija.
