South Africa's former President Jacob Zuma has handed himself in to police to begin serving a 15-month jail sentence for contempt of court.
He was admitted to Estcourt Correctional Centre in his home province of KwaZulu-Natal on Wednesday.
Police had warned that they were prepared to arrest him if he did not hand himself in by midnight.
Zuma, 79, was handed the jail term last week after he failed to attend a corruption inquiry.
The sentencing sparked an unprecedented legal drama in South Africa, which has never seen a former president jailed before.
Zuma had initially refused to hand himself in, but in a short statement on Wednesday, the Jacob Zuma Foundation said he had "decided to comply".
His daughter, Dudu Zuma-Sambudla, later wrote on Twitter that her father was "en route [to the jail] and he is still in high spirits".
