A team of the National Accountability Bureau (NAB) took former army captain Muhammad Safdar into custody minutes after his arrival from London at the Benazir Bhutto International Airport along with his wife Maryam Nawaz.
The couple had arrived to appear before an anti-graft tribunal in connection with the NAB reference pertaining to London properties owned by the Sharif family.
However, Sharif and his two sons were absent as they are in London where 67-year-old Sharif's wife is battling throat cancer.
Sharif attended the previous two hearings but went to London last week to see his ailing wife.
The court held brief hearing and took a break before announcing the hearing will resume shortly. During the brief hearing, Maryam was given copies of the case documents.
Sharif's lawyer also presented an application to exempt him from appearance today as he was with his wife in London.
The trial judge had earlier issued non-bailable warrants for the arrest of Safdar and Sharif's two sons for failing to appear in court in the last hearing held on October 2.
The court, however, repeated the bailable warrants for Sharif's daughter.
"We are going back and will appear before the court and go through the wheels of justice. We respect the rule of law and the Constitution," local media quoted Maryam as saying.
Asked whether her brothers would return to Pakistan to face the NAB references against them, she said, "Hassan and Hussain would themselves tell you about their decision".
Sharif had to step down as prime minister and president of the ruling PML-N party after he was disqualified by the Supreme Court on July 28 in the Panama Papers scandal.
Sharif was re-elected as the president of the ruling PML-N on October 3 and immediately demanded that those who disqualified him should respect the people's mandate and democracy.
