Investigators have traced the HuJI email claiming responsibility for the blast outside the Delhi High Court to a cybercafe in Kishtwar and today detained three persons in this connection including the cafe owner.

Cybercafe owner Mehmood Khawja was detained along with two others for questioning in connection with the Delhi blast, police officials said.

They are being interrogated in connection with the email. One of the detained persons has been identified as Khalid.

Policemen in plainclothes have been deputed outside the cafe in Kishtwar town and are keeping a close watch on the movement of people.

DGP, Mr Kuldeep Khoda, earlier said: “We are investigating the email link from Kishtwar district in connection with the Delhi blast’’.

“We are probing whether there is any link or not with the email from Kishtwar”, he said, adding that police is working on it.

The email was sent from a cyber cafe in Kishtwar from the address harkat-uljihadi2011@gmail.com.

The outfit had yesterday claimed responsibility for the blast outside the Delhi High Court which killed 12 people.

“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 Our demand is that Afzal Guru’s death sentence should be repealed immediately as we would target major High Courts and the Supreme Court of India,” the HuJI email said.

The Secretary (Internal Secretary) in the Home Ministry, Mr U.K. Bansal, had said yesterday that the National Investigation Agency is also verifying the authenticity of the email received by two media channels.

Asked about the communication received by TV channels, the Director-General of NIA, Mr S.C. Sinha, had said, “It is too premature to comment on the HuJI mail but we are looking at it seriously because HuJI is a very prominent terrorist group which considers India as target number one.”

Delhi Police has in the past arrested several HuJI militants from the national capital.
