Jammu, Sep 15 (IANS) Jammu and Kashmir Police and the National Investigation Agency teams Thursday arrested two more people from Kishtwar town of Kashmir for their link to an email that claimed terror group Harkat-ul-Jehadi-Islami (HuJI) had triggered last week's Delhi High Court blast, sources said.

The police sources said that the two -- Amir Abbas Dev and Hilal Asmin alias Hafiz -- were arrested on the basis of disclosure made by two Class 11 students of the town taken into custody Wednesday.

Police sources said that the disclosures made by the two students were being corroborated. "This is a big lead but no conclusions need to be drawn at this moment," an officer associated with investigations told IANS.

The email claiming responsibility of the Sep 7 Delhi blast to the terrorist outfit originated from Kishtwar, 230 km from Jammu. Seven people were detained soon after the email was sent.

The email warned of more attacks if 2001 parliament attack convict, Afzal Guru, now on death row, was hanged. The blast killed 14 people and injured more than 90.

Police Wednesday moved the district and sessions court in Kishtwar to seek remand of the two Class 11 students, who were among the seven detained for their alleged role in sending the email. For reasons of law, names of both students who are juveniles cannot be disclosed.

The court sent the two youths to 10 days in police custody.
