Burkina Faso has frozen the assets of the leader of last week's failed coup, Gen Gilbert Diendere.
Another 13 people suspected of involvement have also had their assets frozen, the state prosecutor says.
Interim President Michel Kafando was reinstated on Wednesday after an intervention from the army and West African leaders.
On Friday, his government ordered the presidential guards' unit that carried out the coup to be disbanded.
At least 10 people were killed and more than 100 injured in clashes during the take-over which Gen Diendere described as "the biggest mistake".
