The son-in-law of ousted premier Nawaz Sharif’s, retired captain Mohammad Safdar, who is serving a one-year jail term at Adiala jail, has been admitted to Pakistan Institute of Medical Sciences (Pims) hospital amid tight security on Thursday after he complained about having abdominal pain.

A notification issued by the chief commissioner states that security will be provided by the Islamabad Capital Territory police.

A five-member medical board, led by Head of General Surgery Dr Tanvir Khaliq, has been formed which will conduct a detailed examination of Safdar. Other members include Assistant Professor of General Surgery Dr Atif Inam Shami, Assistant Professor Gastroenterology Dr Mashood, Assistant Professor of General Medicine, Dr Fibhaa Syed; and Assistant Professor of Radiology, Dr Mujahid Raza.

While his blood pressure was reported to be normal, his sugar levels are raised, according to doctors who also revealed that Safdar had undergone a stomach operation a year-and-a-half back.

Safdar was given one year jail time for not cooperating with NAB, and aiding and abetting Nawaz and Maryam.
