The Uttar Pradesh police have arrested four suspected Harkat-ul -Jehadi Islami men in Lucknow and Faizabad in connection with the Delhi high court blast that killed 11 persons.
Khalid Mujahid, Tariq Qazmi, Sajjad ur Rehman and Khalid Rehman are the four men who are at present in the custody of the UP police.
Although there is no confirmation about their connection with the blast, the police will question them for leads. Two of these men who belong to Jammu and Kashmir region will also be interrogated by the NIA shortly.
NIA sources say that they are seeking the help of the J&K police for further leads. Although the HuJI has a small presence in the valley, there have been intelligence reports of them trying to set up base over there.
The email too has been tracked to a cyber cafe in Kashmir. It is found that the mail was sent from a cyber cafe from Kashmir and bounced off a proxy server from South Africa. However the NIA also doesn't rule out a prank in this issue.
