Datuk Seri Najib Razak arrived at the Kajang Prison at around 6.10pm Tuesday (Aug 23).
He was escorted by the police from the Palace of Justice in Putrajaya.
Earlier, vehicles were seen making u-turns and were not allowed to enter the vicinity of the prison compound.

Crowds could also be seen building up at the roadside at the entrance of the prison.
Najib had left the Palace of Justice at 5.30pm.
The 69-year-old was taken away from the Federal Court in what looked like a black Volvo SUV.

In the last moments before he left the courthouse, his daughter Nooryana Najwa Najib had written a short tribute-like to her father, apologising for not fighting hard enough.
“I’m sorry daddy…
“Maybe we didn’t fight hard enough. Maybe we placed our fullest trust in our justice system. Maybe we believed too whole-heartedly in our cause and purpose so we stood defiant these past four years.
“Yet you did not get your day of justice today, neither did we stand a fighting chance.
“But Bossku does not end here.

“I promise to you that Mummy, Ashman, Abang Jaja, me the family and your people will never rest until you are safely back with us, and justice is served.
“We are so proud of your strength. I will hold on to your parting words of wisdom with me every day.
“They can control everything but they cannot control your emotions and strength of mind.
“Stay strong, Allah is with you my father. Always with you, for now and always,” Nooryana’s Instagram post read.
Earlier, an entourage of police trucks and several cars that included Najib’s wife Datin Sri Rosmah Mansor were seen leaving the court complex.
The police trucks were, however, empty.
Despite the drizzle, around 300 supporters waited patiently near the exit lane behind the building to wave goodbye to Najib.
Avoiding the press, Najib left the court via the entry lane on the other side of the courthouse.
