Sudan’s former President Omar al-Bashir has been moved to Kobar maximum security prison, days after he was deposed in a military coup.
Reports say the ex-leader has until now been detained at the presidential residence under heavy guard.
He is reportedly being held in solitary confinement and is surrounded by tight security.
Months of protests in Sudan led to the ousting and arrest of the long-time ruler on Thursday.
The coup leader at the time, Awad Ibn Auf, said Mr Bashir was being detained in a “safe place” after his removal. He himself stood down soon afterwards.
Lt Gen Abdel Fattah Abdelrahman Burhan was then named as head of the transitional military council, to become Sudan’s third leader in as many days.
Demonstrators have vowed to stay on the streets until there is an immediate move to civilian rule.
