Investigators have also not prepared sketches of terrorists which may help trace them out. The investigation team has yet to start grilling DG National Academy of Prisons, Masood Khan, despite Khyber Pakhtunkhwa IG Prisons Khalid Abbas Khan’s recommendation to Punjab IGP Haji Habibur Rehman for stern action against Masood over negligence in keeping cops at a private hostel without security.

A senior member of the investigation team told this correspondent that they had not received any instruction regarding the national academy DG from IGP Haji Habib so far. He added that Masood Khan would be grilled on receiving instructions from the top cop. The officer also admitted that the negligence of DG/Principal of the academy had resulted in the huge human loss and if he had appointed even a single armed cop at the hostel, the situation could have been different.

“No clue could be found so far,” SSP Investigations Abdul Razzaq Cheema told this correspondent on phone. He said that all the members of joint investigation team were working on the incident, keeping in view different aspects. He said that the evidences, collected from the crime scene, had been sent to the Forensic Lab and its report would be received in a couple of weeks. To a query, the SSP said that the sketches of the attackers would be prepared with the help of injured after they are get well at the hospital.

Meanwhile, the members of the joint investigation team visited the crime scene on Friday and reenacted the attack to ascertain the movement and modus operandi of the assailants. The police teams also recorded statements of locals and under-training jailers who had survived the attack. They collected belongings of the victims, including shoes and clothes, from the crime scene and sealed the hostel. The investigators recovered two hand grenades from the crime scene for forensic tests and collected fingerprints of terrorists from the grenades. However, the investigators have yet to ascertain if the helmet recovered from the crime scene belonged to terrorists.

About the weapons used in the attack, a senior investigator told The News that the terrorists had used AK-47 assault rifles and 30-bore pistols. He added that the empties of bullets, collected from the crime scene, had been sent to forensic lab for tests. He said as the modern forensic tests also provided results of finger prints left on bullets before loading magazine, it would help trace miscreants.

Sources also claimed the terrorists had collected details of the hostel and its surroundings before the attack and they had even mingled with cricket playing boys to know the security situation there. He reiterated the modus operandi was similar to the attack on cops in Gujrat and at Babu Sabu Interchange as the terrorists had used three bikes and a car in the attack.
