Mali's ruling military junta has said it is considering charging the ousted president with high treason.
Coup leader Capt Amadou Sanogo said the junta may also charge Amadou Toumani Toure with financial misconduct.
The announcement came as the junta, which is under fire from the international community, called for a "national meeting" on Mali's future.
Army rebels deposed the government last month claiming President Toure had not done enough to fight Tuareg rebels.
The overthrow of the government has been widely criticised and Mali's neighbours recently imposed sanctions.
