Lahore attack: Important forensic evidence lost

According to forensic expert Dr Ahsan,senior police officials and forensic experts were seen touching and collecting arms and ammunitions without wearing gloves.

The three vehicles taken into custody by the police were also treated carelessly,and no one bothered to preserve the fingerprints or the DNA samples, Dr. Ahsan claimed.

Another forensic expert at the National Centre of Excellence in Molecular Biology,said there were water bottles,disposable cups,Kalashnikov rifles and cartridges,having fingerprints all over them,but security personnel examined them bare handed.

Criminal law expert Aftab Ahmed Bajwa said collecting intact evidence from crime scenes would have offered nothing substantial.
