Police on Friday detained a teenage boy who purportedly sent the Harkat-ul-Jihadi-Islami email claiming responsibility for Wednesday's blast outside the Delhi high court from a cyber cafe in Kishtwar, police said.
The BA first year student was picked up after a three-hour search at a college in Kishtwar and whisked away to Global Cyber Cafe for interrogation by a joint team of police, National Investigation Agency and cyber experts led by Deputy Inspector General (Kishtwar-Doda-Ramban range) Muneesh Sinha.
Police had prepared a sketch of the suspected email sender on the basis of information provided by five detained persons, including cyber cafe owner Masood Aziz.
Investigators had traced the HuJI email claiming responsibility for the blast to the Global Cyber Cafe in Kishtwar.
The cafe has been sealed and policemen in plain clothes have been deputed outside the shop. A team of NIA and experts from Hyderabad are in Kishtwar to probe the email link with the Delhi blast that killed 13 people.
HuJI had on Wednesday claimed responsibility for the blast.
"We own responsibility of the blast at the High Court, Delhi. Our demand is that Afzal Guru's death sentence should be repealed immediately as we would target major High Courts and the Supreme Court of India," the HuJI email had said.
