Imphal, Aug 17: One day after the bomb attack at ISKCON left four dead and injured scores of other devotees, the State police is yet to zero in on any clue to could lead to the perpetrators of the ghastly crime.

On being contacted, IGP (LO-1) R Baral said, "As of now we have not been able to find any solid clues but investigation is on in full swing." To a question whether the attack could be the handiwork of some religious fundamentalists, the police officer said, "It is too early to say anything and so far no organisation has claimed responsibility for the attack." Another police officer said that if ISKCON authorities provide information on the probable reason for the attack, then the investigation will be much easier.

No arrests have been made till date.

Imphal West SP Clay Khongsai however said, "We have a little idea on the case but we cannot spell it out at the moment." On the part of security deployment at ISKCON on the fateful day, the SP replied, "I don't think there were any security lapses on our part." ISKCON had submitted an application to the police to help in monitoring the flow of the traffic and to control the crowd, said the SP and added that adequate personnel were deployed as asked.

Meanwhile, ISKCON temple president Ajit Das said that the Imphal office has received an intimation from the Centre that a special flight may be flown in to evacuate ISKCON members from outside Manipur.

"We will reply soon as some of the foreigners are still undergoing treatment," said Das.

Bryan Nash of California and Radhika Pyari Devi Das of Iran (granted Indian citizenship) are undergoing treatment.
