RAWALPINDI, Aug 24: Investigators probing into the Thursday’s twin suicide bombings outside the Pakistan Ordnance Factories (POF) in Wah Cantonment have taken four more persons, including a prayer leader, in their custody, Dawn has learnt.

The investigators are still desperately hunting for a man who used to pick and drop the three suicide bombers, including detained 17-year-old Hameedullah, in his black-coloured car, a source close to the investigation revealed.

Hameedullah, an alleged accomplice of the two suicide bombers who struck at the Pakistan Ordnance Factories gates, disclosed during interrogation that a man in a black-coloured car used to drop them near Aslam Market and later picked them up from the same place in the evening.

He further revealed that he was given the task to blow himself up among “foreigners” leaving the Pakistan Ordnance Factories gates, but when he did not see the target he changed his mind and went to the toilet of a mosque where he removed his explosive-vest and left the scene, the source said.

However, he was captured by the security officials while fleeing.

Hameedullah, who is from the Khyber Agency, has been in remand custody after his arrest.

According to the source, the two suicide bombers were aged between 16 and 17.
