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.
