Police had got vital clues about the person who had sent an email claiming responsibility for the Delhi High Court blast after raids on a cyber cafe in Kishtwar in the state, officials said Thursday.
On questioning owners of the Global Internet Cafe in Kishtwar, about 230 km from here, investigators garnered some information about how the man looked.
"We have got some details about the physical features of the person. Police parties have been deputed to trace him," a senior police officer working on the investigations told IANS.
No formal arrest had been made so far, he said.
The owners, Khajwa Mehmood Aziz and his brother Khalid Aziz, were being questioned and police were scanning the records of the cyber cafe and the people who visited it Wednesday.
Jammu and Kashmir Police had conducted raids after it became known that the email, purportedly by Harkat-ul Jehadi Islami, had been sent from a cyber cafe in Kishtwar.
The National Investigation Agency zeroed in on Global Internet Cafe at Malik Market in Kishtwar as the place from where the email was sent.
The Pakistan-based HuJI had sent the email to two television channels demanding that the hanging of 2001 parliament attack convict Afzal Guru be immediately repealed.
The records of mails and details of all those who sent it are being scanned, they added.
Twelve people were killed and 91 injured when a powerful bomb concealed in a briefcase exploded at a gate of the high court in New Delhi Wednesday morning.
