Within 48 hours of a high intensity bomb blast that killed 13 people so far and left more than 70 injured at the Delhi High Court, investigators received yet another e-mail allegedly from banned terrorist organisation Indian Mujahideen (IM). This is a second e-mail since Wednesday which was sent by a terrorist organisation claiming responsibility for the attack.

Hours after the blast on Wednesday, an e-mail claiming responsibility for the terrorist attack was allegedly sent by members of the banned Harkat-ul Jihad Islami (HuJI). "HuJI was not responsible for the blast, it was carried out by the Indian Mujahideen. We had made plans to target Delhi High Court for long and we decided to do it on Wednesday because it is the busiest day at the Delhi High Court," claims the e-mail said to be sent by Indian Mujahideen (IM) on Thursday. "We will again carry out an attack on Tuesday outside a shopping complex. Stop it if you can," it further stated.

The email allegedly sent by 'Chotu' who claims to be a member of the Indian Mujahideen and used a Gmail address. "We are taking this second e-mail very seriously and investigations are going on," said Indian Internal Security Secretary UK Bansal. The home ministry has already approached Google to help track down the e-mail. Meanwhile, the National Investigation Agency (NIA), which is spearheading the blast probe, announced a reward of INR500,000 (PKR 948,000) to anyone who provides information about the terrorists involved in the blast. NIA chief SC Sinha also met Delhi Police commissioner BK Gupta and members of the special cell (anti-terrorist unit) to discuss the ongoing probe. Apart from tracking organisations like HuJI and IM, intelligence agencies are also tracking members of the Khalistan Zindabad Force (KZF), Khalistan Commando Force (KCF) and Babbar Khalsa International (BKI), suspecting their involvement in the blast.
