PESHAWAR, May 16: Investigators probing Tuesday’s bomb blast in Peshawar have sent the legs of the suspected suicide bomber for laboratory analysis to determine his age, official said.

“We also have sent specimens from the remains of the alleged suicide bomber for DNA tests,” said police officer Fayaz Toru.

He said the legs of the alleged bomber had been sent for forensic and radiological examination to determine his age. The result of the tests would be available by tomorrow.

Another investigator said the alleged suicide bomber appeared to be in late sixties. That, said the investigator, was different from past suicide bombings where young boys in their late teens and early twenties were the perpetrators.

Also, he said, the suicide bomber in the Tuesday’s incident had tied a suicide note around his legs, which again was a change from the past tactics.

The note warned that those spying for the US would meet a similar fate. The investigator said the bomber had used Russian-made explosives of between four to five kilograms and the initiator or trigger recovered from the scene indicated it could be part of the series of suicide bombings that had hit the country in recent months.

The investigator denied the reported arrest of a relative of the now-dead Taliban commander Mullah Dadullah from the restaurant. “No arrests have taken place here. This is all hogwash,” he said.

But, he said, investigators were trying to establish the motive for the suicide bombing at a public place.
