Jaipur/Udaipur, May 16: Illegal Bangladeshi migrants in Rajasthan will be identified in 30 days and could be deported as they came under the scanner of the state government after the serial blasts while a hotelier claimed he saw one of the suspects in Udaipur two days before the attack.

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.

The State's Principal Home Secretary discussed with his Central counterpart today 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 last night was seen along with a woman in his restaurant on Sunday evening.

On the probe front, Rathore said sleuths of the Special Task Force were working on a number of leads including use of bicycles, bags, and the e-mail carrying some videos clips that was generated from a cyber cafe in Ghaziabad.

Four sketches have been released so far and more were being readied based on clues given by the eight cycle owners, Rathore said.

Ten bicycles were bought about two-three hours before the actual blast from the Kishanpole Bazar cycle market, he said, adding the purchase of eight were confirmed while sellers of the other two were being traced.

Of the ten cycles tagged with explosive bags, only nine blasted, and one was recovered and its bomb was later diffused by the experts.

The minister denied of any official circular from the Union Home Minister that hinted of terror attack in Rajasthan in recent months.

Rathore said 64 people had died in the blasts and of the 141 injured, 108 are in serious condition. Fifty-one bodies have been identified, and an ex-gratia of Rs five lakh each paid to their relatives.

DIG (Crime) Saurabh Srivastava said 18 people have been interrogated so far in connection with the blasts.
