The joint team investigating the suicide attack on a Muharram procession in the Dhoke Syedan locality of Rawalpindi has failed to make any breakthrough in identifying the suicide bomber, it has been learnt.

The fingerprints of the bomber, who had been described by the police as a teenage boy, could not be matched with the record of the National Database and Registration Authority (Nadra).

Four samples taken from different body parts had been sent to the laboratory in Lahore after the suicide bomber hit the procession on November 21 killing about 20 people.

The joint investigating team is also unable to trace the place where the suicide bomber had stayed before hitting the procession.

The JIT, comprising officers from the counter-terrorism department and police, has been investigating the incident on different lines.
