Guwahati, Nov. 5: Police will not release the sketches of two more suspects in Thursday’s serial blasts as those match the profiles of criminals in their files.

Sources today said the sketches of the two persons would now be held back as these have already tallied with persons known to investigating agencies. The task now is to hunt them down.

The police yesterday released the sketch of one suspect involved in the blast at the CJM court. The sketch was drawn on the basis of descriptions by eyewitnesses, who also certified it to be 70-80 per cent accurate.

The investigators were yet to get any clue about the identity of the person whose sketch was released yesterday. “Every security agency and informer have been given a copy of the sketch. Hopefully, something will turn up,” a source said.

He said apart from posting the sketches to official channels, these would be taken to those undergoing treatment in hospitals to see if they could throw any light on them.

The source said the police would interrogate a resident of Srinivaspuri of New Delhi in connection with the blasts but refused to elaborate except to say,“We hope to get some important leads for our investigation from him”. They did not even reveal his profession.

The source said the state police would get in touch with Delhi police in this connection. “From the investigations carried out so far, it appears that the serial blasts in Assam were masterminded by an external intelligence agency of a neighbouring country and carried out with the help of their network of local sympathisers and sleeper cells,” he said.

The security forces have launched a hunt to apprehend Mukut Ali of Nalbari district — a petty criminal involved in car thefts — as evidence pointed to his involvement, even if indirectly, in the serial blasts.

The police today confirmed that the Maruti 800 car used in the Ganeshguri blast was bought in 1996 from Buishi Yada Motors, a dealer of Maruti at Itanagar.

The origin of the car purchased from Itanagar was traced from its engine number 3043461 and chassis number 2016720. The police have ascertained that the first owner of the car was no more.

They said investigations were on to ascertain the current owner and appealed to the public to immediately contact the police if they have any information that would expedite the investigations. The police said the identity of the informer(s) would not be disclosed and the informer(s) would also be rewarded.
