New Delhi: Officials investigating the Parliament bomb scare case are facing an uphill task in Tamil Nadu as the cybercafes in the state, from where the e-mail warning of the attacks was sent, do not have proper log book entries about their customers.

"It is still a blind case. There are no proper entries in the customer log books at the cyber cafes," a senior official investigating the case said here.

Tamil Nadu Police has picked up about a dozen people for questioning at Palayamkottai town in Tirunelveli from where the e-mail warning of attacks on Parliament and American Embassies was sent.

Both houses of Parliament were abruptly adjourned on Friday after receiving the threats and after a thorough search of House the threat was declared a hoax.

The Special Cell of Delhi Police had registered a case against unknown persons in this connection and despatched a four-member team to Tirunelveli to investigate the matter.

Tamil Nadu Police has been interrogating those detained and trying to draw a sketch of the person who is believed to have sent the e-mail.

The questioning is being done to get a description of those who visited the two browsing centres at the time the e-mail threat message originated, officials said.

Most of the interrogation is being done by the local police, who are better placed considering the local language and the dialects.

Among those questioned was a lecturer of the Tirunelveli city college and a non-teaching staff.
