Sources also claim that Delhi police is on a lookout for a Santro or a Hyundai i10 and investigators are also probing into any possible emails from J&K. Investigators are also trying to establish an IP address which was used to send the e-mail.
Hours after the powerful bomb blast that shook the national capital on Sept 7, Harkat-ul Jehad al Islami (HuJI) claimed responsibility for the blast.
The authenticity of the email is also being verified, said intelligence sources. The terror group HuJI also claimed to have sent mails to two media houses from a mail id: firstname.lastname@example.org.
Sources also claim that the e-mail did not use any shortened name or was typical HuJI move.
