During the hearing Justice Gulzar Ahmed remarked that it was a high-profile case and all the accused had not been identified yet.

Deputy Inspector General of the Crime Investigation Department (CID) Sultan Khawaja informed the court that all secret agencies had held a meeting over the case. He added that the Board of Revenue had yet to respond to a request sent to it.

Justice Gulzar replied that time was being sought for the past six months even though all systems in the country have been computerised. He told the DIG-CID to head the probe in the right direction and added that personnel at police stations were aware of everything.

The court directed for the continuation of the probe to ascertain all culprits and also sought a report over the progress in the case during the next hearing which was adjourned until December 15.

Parveen Rehman, a media-shy social worker who devoted her life to the development of the impoverished neighbourhoods across the country, was gunned down near her office in Karachi's Orangi Town on March 13, 2013.

The very next day, police killed a Taliban operative named Qari Bilal in an encounter and claimed he was the murderer, resulting in a closure of the case.

The Supreme Court of Pakistan on April 15 this year ordered authorities to conduct a fresh probe into Parveen Rehman's murder after a judicial inquiry had revealed that police officers had manipulated the investigation
