Captain (retd) Safdar's condition deteriorated at Adiala prison late Monday, sources said, after which the son-in-law of former premier Nawaz Sharif was being given medical attention inside the jail.
The sources informed that a decision to shift Safdar to hospital had yet to be made.
The son-in-law of the deposed prime minister was arrested by the National Accountability Bureau on July 8, following an accountability court's verdict in the Avenfield properties corruption reference in which Nawaz and his daughter were also sentenced.
The court had sentenced Nawaz to a total of 11 years in prison and slapped a £8 million fine (Rs1.3 billion) in the corruption reference while his daughter Maryam was sentenced to eight years with a £2 million fine (Rs335 million).
Nawaz's son-in-law was given a one-year sentence without any fine. He has since been serving his term at the Adiala prison.
On August 9, Safdar was shifted to the Pakistan Institute of Medical Sciences (PIMS), Islamabad from the prison after his condition worsened.
