The Gambia’s former president stole “at least” $50m (£38.4m) from the state before he left the country in January, the justice minister has said.
Yahya Jammeh is accused of withdrawing the money via a state telecoms company.
A court has ordered all his remaining assets in The Gambia to be frozen.
Mr Jammeh flew into Equatorial Guinea after 22 years in power. He lost an election in December and only agreed to step down after regional powers sent in troops threatening to force him out.
Luxury cars and other items were reportedly loaded on to a Chadian cargo plane as Mr Jammeh left the country.
The amount was initially suggested to be more than $11m (£8.8m) by Interior Minister Mai Ahmad Fatty then an aide to new President Adam Barrow.
But on Monday, Justice Minister Abubacarr Tambadou said that Mr Jammeh had withdrawn $50m between 2006 and 2016.
