Extradition is an official procedure under which a country transfers or hands over a person suspected of or convicted in a crime to another country. Generally, this process is governed by treaties between countries. In case extradition is bound by laws as in among sub-national jurisdictions, the concept is generally referred to as rendition. Extradition is believed to be an age-old procedure, dating back to the thirteenth century BC when it was supposed to have been practiced by an Egyptian pharaoh.
Via this process, a sovereign makes a formal request to another sovereign to hand over the person(s). If the wanted person is found within the territory of the requested nation, then this nation can arrest the person (fugitive) and subject him/her to its extradition process.
