The International Criminal Court prosecutor at The Hague is seeking Interpol's help in arresting fugitive Libyan dictator Muammar Gaddafi.
Luis Moreno-Ocampo is asking the international police organisation to issue so-called "red notices" for Gaddafi and says arresting him is a "matter of time".
Mr Moreno-Ocampo's office in the Netherlands also announced he has sought Interpol's help to arrest Gaddafi's son and one-time heir apparent Saif al-Islam, and the regime's intelligence chief Abdullah Al-Sanoussi.
All three men are accused of crimes against humanity for unleashing a campaign of murder and torture since February in an attempt to crush dissent.
The court issued arrest warrants for the three men in June, but has no police force to detain the suspects.
