Former premier Nawaz Sharif and his daughter Maryam Nawaz were arrested by National Accountability Bureau (NAB) officials upon their arrival in Lahore on Friday night, and subsequently whisked away to Islamabad on a chartered flight.
The two were separated and taken from the Islamabad International Airport in two convoys to the Central Jail in Adiala, Rawalpindi, for a medical examination.
As per official procedure, the examination was carried out in the presence of the Islamabad magistrate and senior police officials.
The penitentiary's medical board compiled reports on Nawaz and Maryam's medical history and declared them fit for incarceration in the facility.
Nawaz spent the night in one of the rooms of the jail's high security zone, whereas Maryam was transferred to the women's barracks.
Meanwhile, a NAB prosecution team had approached the accountability courts seeking an exemption for Nawaz and Maryam's appearance before the court. NAB Additional Deputy Prosecutor General Sardar Muzaffar Abbasi told the court that the convicts cannot be produced before the court due to a high-security risk.
The accountability court conceded the request and appointed Magistrate Wasim Ahmed to execute the warrants of imprisonment at Adiala. By this exercise, the authorities eliminated any chance of producing Nawaz and Maryam before the court the same night or next morning.
Media representatives who had gathered to cover the production of Nawaz and Maryam before the court were not allowed to enter the premises of the court complex.
