The Uttar Pradesh police on Tuesday said fresh sketches of the perpetrators of the Varanasi twin blasts will be obtained with the help of some renowned artists.
Two weeks after the blasts, the police have made no headway in the case.
UP Director-General of Police Yashpal Singh told PTI that the sketches by the two artists, released earlier by the Varanasi police have not given them any clue about the real culprits.
"Services of some renowned artists could now be obtained for making fresh sketches of the suspects so that the real culprits could be arrested and the case worked out," he said.
The DGP told NDTV that the senior superintendent of police released the earlier sketches of the two suspects behind the blasts 'hurriedly'.
"This was a fault on the part of the SSP (Varanasi). Perhaps he has realised it also. He should not have done it so fast. He should have verified it in detail."
On the basis of the sketches, two persons, who resembled the suspects, were arrested from Hardoi, UP, but they had to be let off after sustained interrogation proved that they were innocent, Singh said.
"There is only one artist who is dependable. He is from Mumbai. I had particularly asked the SSP to call him and get the sketches made by that very artist. But unfortunately, there was some hurry, which was not very useful for our investigation," the DGP said.
"It has not affected the investigation, but it has not helped us in any way," he added. Singh said the Special Task Force will be able to crack the case soon.
