More than $11m (£8.8m) is missing from The Gambia’s state coffers following the departure of long-time leader Yahya Jammeh, an adviser to President Adama Barrow has said.
Mai Ahmad Fatty said financial experts were trying to evaluate the exact loss.
Luxury cars and other items were seen being loaded on to a Chadian cargo plane on the night Mr Jammeh left the country.
Mr Jammeh flew into exile on Saturday, ending his 22 years in power.
He had refused to accept election results but finally left after mediation by regional leaders and the threat of military intervention.

President Barrow remains in neighbouring Senegal and it is not clear when he will return.
However, West African troops have entered the Gambian capital, Banjul, on Sunday to prepare for his arrival.
Cheering crowds gathered outside the State House to watch soldiers secure the building.
The Senegalese general leading the joint force from five African nations said they were controlling “strategic points to ensure the safety of the population and facilitate… Mr Barrow’s assumption of his role”.
Mr Fatty told reporters in the Senegalese capital Dakar that The Gambia was in financial distress.
“The coffers are virtually empty,” he said. “It has been confirmed by technicians in the ministry of finance and the Central Bank of the Gambia.”
