Shyam Bir, owner of the cyber cafe in Sahibabad town, and his employee were taken for questioning late Wednesday night by the Special Task Force (STF) of the police, District Superintendent of Police Deepak Ratan said.

The email was purportedly sent by militant outfit 'Indian Mujahideen' to TV channels on Wednesday, claiming responsibility for the blasts and giving details of a bicycle allegedly used in one of the explosions at Choti Chaupad in Jaipur.

Police also raided a house in Baghpat district in its hunt for one Shamim, chief of the western UP unit of Harkat-ul Jehadi Islami (HuJI) of Bangladesh, who is suspected to be involved in the Varanasi serial blasts in 2006.
