Mumbai, July 16 (IANS) Claiming to have secured "solid leads" in the 13/7 blasts here, a top Mumbai police official said Saturday that the investigations are now moving in "a certain direction" and the sketch of one suspect will be ready soon.


This has been made possible by a witness to the incident at one of the three locations, said Maharashtra Anti-Terrorism Squad (ATS) chief Rakesh Maria, refusing to identify the blast site where the witness was present.

Maria also said that the role or involvement of the underworld in the explosions, which left 19 dead and over 100 injured Wednesday, was being examined.

He denied involvement of a suicide bomber.

The three serial blasts in Dadar, Zaveri Bazar and Opera House Wednesday evening were the first terrorist attack in the financial hub of the country after 26/11.

Investigators examined the CCTV image of an unidentified individual suspected to have planted a bomb at one of the three blast locations.

"We do have a photograph at one of the locations through the CCTV, which needs more verification and investigation. Our teams are on the job to know who that individual is," Maria said.

He said investigators from various agencies were probing the blasts and "are confident of being able to do justice with the investigation".

Maria said that the CCTV footage collected from all the three blast sites was "grainy" and was being improved by experts. "The image enhancing may take 24-48 hours to have a clearer image of that individual," Maria said.

He said that investigating teams were in touch with police forces of different states, including Uttar Pradesh, Gujarat, Delhi, Andhra Pradesh, West Bengal and Madhya Pradesh.

He said it was "not fair to pinpoint" that any particular group was involved in the blasts.
