Investigators got fresh leads like ten bicycles having been bought about two to three hours before Tuesday night's blasts that left 64 dead but a breakthrough eluded them.

With the Bangladesh-based HuJI being suspected to be behind the blasts, state PWD Minister Rajendra Singh Rathore said the state government is on a hunt for Bangladeshis with suspected criminal background. Forty such Bangladeshi nationals have been rounded up so far and are being interrogated, he said.

Eight of them were detained in Ajmer. All District Collectors and Superintendents of Police have been directed to complete within 30 days the process of identifying Bangladeshi migrants living with or without voter ID cards and/or ration cards and get them verified, Rathore said.

The procedures for deporting the identified illegal nationals could then be started, he said. The process has begun everywhere in the state, he added. On Friday the State's Principal Home Secretary discussed with his Central counterpart the option of deporting illegally staying Bangladeshi nationals, he added.

Rathore sad 141 people were injured of whom 108 were in a "very serious." condition.

The owner of SamorBagh restaurant in Udaipur Kamal Joshi was interrogated by police after he claimed today that a person bearing resemblance to one of the sketches of suspects released on Thursday night was seen along with a woman in his restaurant on Sunday evening.

Joshi told the police that the man was accompanied by a young woman and both of them came to the restaurant at about 4 PM on Sunday.

The woman entered the restaurant wearing a saree but changed into a salwar kameez before leaving with the man, Joshi said, according to the police. They did not take anything in the restaurant, he said.

The in-charge of Surajpole police station Himmat Singh said investigations were on to check the movement of the duo in Udaipur.

Regarding the blasts probe, Rathore said sleuths from the state, Uttar Pradesh and Andhra Pradesh were working on a number of leads including use of bicycles, bag, and e-mail received from Ghaziabad.

Rathore said the purchase of eight cycles which were used in the blasts were confirmed but the sellers of two more cycles were yet to be identified.

A car seized by the Railway police outside Jaipur station on Thursday night belonged to one Afzal who went to Chennai to visit his ailing mother and left the vehicle in the no-parking zone, Rathore said. The police was investigating the matter following suspicions that it may have been used by the cycle bombers.
