NEW DELHI: Two days after the high intensity blast at the Delhi High Court, investigators were groping for a breakthrough even as the Home Minister, Mr P Chidambaram Friday said there were “promising leads” in the probe.

On a day two more emails purportedly sent by Indian Mujahideen were received by Delhi police and media houses, Mr Chidambaram did not rule out cross-border connection saying, “At this moment, every organisation is suspect” and he was “keeping fingers crossed till we have evidence.”
The IM claiming responsibility for Wednesday’s blast that left 13 dead and 88 injured, also warned the government of another attack “that will be so cruel that you people will not be able to forget it” for decades.
“...And if you are willing to know the next attack, it is 1,8,5,13,4,1,2,1,4 till you come to know what it stands for, the next blast will be done. If you have any questions because we don’t have time for anything,” the sources said, quoting the e-mail.
The email received by Delhi police headquarters is claimed to have bounced from various Internet gateways with the server finally traced to Moscow, official sources said.
A fourth email sent to media houses by Indian Mujahideen’s ‘Chotoo’ warned of a major terror attack in a ‘crowded’ place in Ahmedabad.
A person, suspected of sending e-mail immediately after the blast, has been taken in for questioning in Kishtwar in Jammu and Kashmir. “We have to wait for that report to come,” Mr Chidambaram said.
Amid concerns over security in the Supreme Court, the Prime Minister, Dr Manmohan Singh stepped in and directed urgent steps to beef up protective measures in the complex. He asked Mr Chidambaram and the Law Minister, Mr Salman Khurshid to call on the Chief Justice of India, Mr Justice S H Kapadia and take “urgent steps” to further strengthen the security arrangements.
Around 200 policemen spread in three teams led by two Deputy Commissioners will look for leads into Wednesday’s blast outside the Delhi High Court even as Delhi police strengthened its security apparatus keeping in mind the coming festive season.
The teams, under Deputy Commissioners of Police, Mr Ashok Chand (Crime) and Mr Arun Kampani (Special Cell), will interact with the National Investigation Agency (NIA), which has been entrusted with the probe of the blast case, Delhi Police Commissioner, Mr B K Gupta said here Friday.
Police is also in the process of releasing a third sketch of a suspect in the blast, which claimed 13 lives and injured nearly 90. Mr Gupta said the three teams formed under Mr Chand and Mr Kampani will have regular interactions with the NIA which is probing Wednesday’s blast.
“They will interact with NIA. The teams will conduct investigations and senior officials will be reviewing it every third or fourth day. We have brought together best resources and also officers who have experience in handling such cases have been asked to join the group,” he said.
Mr Gupta said the teams have been given full “operational freedom” in carrying out investigations. He also said CCTV cameras will be installed in 44 places in a month’s time and that ECIL will install the same at all court premises. A senior police official said their hands were full as the anniversary of 2008 blast and the Batla House encounter was approaching as well as Dusshera and Navaratras.
