South Africa's former President Jacob Zuma has handed himself in to police to begin serving a jail sentence for contempt of court, reports BBC.
He travelled to a prison near to his home in KwaZulu-Natal province late on Wednesday, his foundation said.
Police had warned they were prepared to arrest the 79-year-old if he did not hand himself in by the end of the day.
Mr Zuma was given a 15-month jail term last week after he failed to attend a corruption inquiry.
The sentencing sparked an unprecedented legal drama in South Africa, with a deadline imposed of midnight on Wednesday (22:00 GMT) for his arrest.
The deadline was imposed after Mr Zuma refused to hand himself in on Sunday.
"President Zuma has decided to comply with the incarceration order," his foundation said in a short statement.
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".
South Africa has never seen a former president jailed before.
Mr Zuma was handed the 15-month sentence on 29 June for defying an instruction to give evidence at an inquiry into corruption during his nine years in power.
Businessmen have been accused of conspiring with politicians to influence the decision-making process while he was in office. But Mr Zuma has repeatedly said that he is the victim of a political conspiracy.
Though he was forced out of office by his own party in 2018, the African National Congress (ANC), he retains a loyal body of supporters, especially in his home province of KwaZulu-Natal.
On Sunday, crowds formed what they called a human shield outside Mr Zuma's palatial home in an effort to prevent his arrest. Similar crowds gathered before he handed himself in on Wednesday.
The BBC's Nomsa Maseko, who was outside Mr Zuma's home on Wednesday, noted that there was a large police presence outside the property that included armed officers and a paramilitary unit.
A delegation of senior officers are believed to have spent several hours inside the residence negotiating with the former president over his arrest.
A convoy of cars, one of which was carrying Mr Zuma, was then seen leaving the house at high-speed shortly before the midnight deadline for his detention.
Mr Zuma previously declared that he was prepared to go to prison.
However, he said that "sending me to jail during the height of a pandemic, at my age, is the same as sentencing me to death".
Mr Zuma has also repeatedly said that he is the victim of a political conspiracy. He has testified only once at the corruption inquiry into what has become known as "state capture" - meaning the siphoning off of state assets.
In a separate legal matter, Mr Zuma pleaded not guilty last month in a corruption trial involving a $5bn (£3bn) arms deal from the 1990s.
