The bicycle, shown in the incriminating e-mail discovered to have been sent from a Ghaziabad based cyber cafe to offices of two prominent Hindi television news channels after the Jaipur blast on Wednesday, does not match with the one used in the actual blast.

Disclosing this on Thursday, Uttar Pradesh Additional Director General of Police Brij Lal who also heads the state Special Task Force, told rediff.com, "The bicycle used in the blast looks like a racing model with a straight handle while the one visible on the e-mail was an ordinary one."

He said, "Furthermore, while reports from Jaipur suggested that the explosives used in the blast were tied to the handle of the bicycle, the e-mail visuals show explosives planted on the bicycle carrier at the back."

Even as STF sleuths had fanned out to track down the person, who had used the cyber cafe to send the suspicious mail, Lal does not rule out the possibility that the mail was simply aimed at pulling a fast one. 

A team of UP's Anti-Terrorism Squad had reached Jaipur early Thursday morning to evaluate whether there was a close similarity between blasts over the past two years in different UP towns and Wednesday's deadly blast in Jaipur.

Earlier late Wednesday night, STF personnel traced the e-mail to a cyber cafe in Sahibabad, a suburb of Ghaziabad close to the border of the national capital, New Delhi.

Cyber cafe owners, Madhukar Misra and his father Sia Ram Misra, have been under STF detention since then. Cops, however, rule out their involvement.

Based on the details given by the father and son, STF sleuths have drawn a sketch of the suspect who issued the mail. "We hope to zero in on the culprit soon," Lal asserted.
