ISLAMABAD: Chief Justice of Pakistan (CJP) Mian Saqib Nisar on Tuesday grilled the Pakistan Tehreek-e-Insaf (PTI) chief;s counsel over his client's source of income for purchasing his Bani Gala estate.

A three-member bench led by the chief justice heard the case filed by Pakistan Muslim League-Nawaz leader Hanif Abbasi against PTI Chairman Imran Khan. 

Abbasi's petition accuses the PTI leader of not declaring his assets to the Election Commission of Pakistan (ECP) and seeks to unseat him based on alleged violations of the Income Tax Ordinance 1979 and Peoples Act 1974.

During Tuesday's hearing, the CJP remarked that the money trail of one of Khan's accounts is vague.

In response to PTI counsel Naeem Bukhari's statement that the PTI chief was able to purchase property through his income from playing cricket, the bench inquired about details of the former cricketer's savings and documentation of bank accounts.

Bukhari said he would provide the details to the court. 

This is a developing story and will be updated as more information is received.
