Ousted Libyan Prime Minister Ali Zeidan has been barred from travelling outside the country by the country's general prosecutor, Abdelkader Radhouan
Zeidan lost a confidence vote by the General National Congress (GNC-parliament) on Tuesday, and was replaced by Defence Minister Abdallah al-Theni.
According to the prosecutor, Zeidan may be involved in financial allegations running to 30 million Libyan Dinars (US$23.8 million), which is the sum given to armed groups that blocked oil fields in the eastern part of the country.
In August 2013, the head of the energy commission at the GNC, Nagi Mokhtar, had given to the brother of an armed group's chief that control oil fields in the east, Brahim Jodharane, a cheque of 30 million Libyan dinars to lift the blockade.
The money may have come from some departments under the former Premier.
Some Libyan television stations reported that the former PM had already left the country aboard a private plane, but the information could not be independently confirmed.
Mr. Zeidan had survived thus far because of lack of quorum in the GNC.
The Premier was ousted following the escape of a North Korean tanker, which was loaded with oil being sold illegally by militants.
