There had been an international arrest warrant against KaradÅ 3\/4 iÄ for more than a decade .
After a failed raid earlier in May , on 7 July 2005 NATO troops arrested KaradÅ 3\/4 iÄ 's son , Aleksandar ( SaÅ a ) KaradÅ 3\/4 iÄ but released him after 10 days . On 28 July , KaradÅ 3\/4 iÄ 's wife , Ljiljana Zelen KaradÅ 3\/4 iÄ , made a call for him to surrender after , in her words , `` enormous pressure '' had been put onto her .
