A team led by NAB Deputy Director Raheel Azam left the prison facility for Islamabad after grilling the former prime minister for around seven hours.

During the investigation, the anti-graft body team asked several questions regarding different documents and evidence related to the case.

A day earlier, Judge Muhammad Bashir presided over the hearing in the case in Adiala Jail, where the anti-graft body asked for a 10-day remand.

However, the judge only approved a four-day remand and adjourned the case till November 21. The court also extended Bushra Begum’s bail in the case till November 21.

Soon after the court’s verdict, a three-member team of the NAB arrived at the jail and interrogated the PTI chief for two and a half hours.

Khan is already being held in jail in the cypher case, registered under the Official Secrets Act, whose trials have exclusively been held in jail.

However, authorities recently obtained warrants for his arrest in the Toshakhana case and £190 million case. He was subsequently arrested from jail.

Although, the IHC restored his bail application in the Toshakhana case but he continues to be under arrest in the £190 million case.
