Two days after the e-mail by one Guru Al-Hindi surfaced claiming responsibility for the Jaipur serial blasts, technical investigations have revealed that the text of the e-mail was first drafted about a month ago. It was continuously edited until a final version was firmed up two weeks before the explosions.The five-page note claiming responsibility and giving reasons for the attack that killed over 70 people was written separately on a MS Word document, which was later attached to the e-mail. The e-mail id guru_alhindi_jaipur@yahoo.co.uk, sources said, was created only a day before the attack. Detailed technical investigations were carried out on the text in the last 24 hours and it was found that the first draft was made at least a month ago, indicating the level of preparations that went into the terror attack.Most of the editing that was done on the text in the next two weeks, sources said, was aimed at making the content “more rabid.”In the five-page e-mail, the group essentially talks of a three broad motives — target places of religious faith, attack tourists and take revenge for the “atrocities” committed against Muslims.There is also a small message for the “Indian police force”, warning them not to arrest Muslims. Calling themselves “Indian Mujahideen”, the group claims to have divided itself into three wings: a Shahbuddin Gouri brigade to attack South India, a Mahmood Ghaznavi brigade for North India and a Shaheed Al-Zarqawi brigade to carry out suicide attacks.The e-mail was sent from an internet café in Sahibabad area of Ghaziabad whose owners have been detained for questioning. While the state government had issued orders for all internet café owners to maintain a proper log of customers, sources said, authorities were now finding a way to book and arrest the two owners who had not kept the vital records. In most states, the arrest would be possible under the IT Act, but a notification to this effect ought to have been issued by the state government. Besides the e-mail, investigators are working on claims made the owner of one Samorbagh Restaurant in Udaipur that a man resembling the face of the first sketch put out by the Rajasthan police had visited his restaurant two days before the blast. He has claimed that a woman, who even changed her clothes at the restaurant, accompanied the man.Meanwhile, separate investigations are underway on the explosives obtained from the ninth bomb that was defused before it could explode. The identical nature of the explosives used in Jaipur with that of the Hyderabad blasts last August is under careful scrutiny.
