However, the FIA did not make any changes in the investigation process and the witnesses in the case. According to the new challan, arrest warrants were re-issued by the FIA. The court sought a report on the arrest warrants of the suspects till June 11, reports The Express Tribune. Mohammad Amjad Pervaiz, the lawyer representing Shehbaz Sharif and Hamza Shehbaz began his arguments for the latter's bail. He contended that the case had been investigated for one and a half years and but still no proof was on record, adding that the father and son were in jail and were also interrogated in the case. "Even though they were already in jail, the FIA instead of taking them into custody remained silent for months." /IANS
