Investigators continued to grope for definite leads two days after the Mumbai terror attack as they identified the scooter in which explosives were hidden at one of the three bomb sites,quizzed several people and analysed call records.
Asked whether the investigators were working on any definite lead,Union Home Secretary R K Singh said “we have not yet zeroed in on”.
Officials said an explosive cocktail of Ammonium Nitrate,TNT and fuel oil along with a timer were planted in the boot of the scooter outside Opera House to create maximum damage since the ripped metal would become like splinters.
Investigators have pinned their hopes on the details of scooter parked outside Opera House to give some clues.
“We have identified the scooter in which one of the bombs was planted,” Singh said.
The chassis number of the scooter was scratched by the perpetrators of the triple explosions but was later retrieved by the investigators. 18 people have been killed in the triple explosions on Wednesday evening.
The attempt was apparently aimed at misleading the probe in a different direction,they said. The Gujarat registered two-wheeler was in Mumbai for many months.
It may be recalled that the motorcycle used in Malegaon 2008 blasts had its chassis number damaged.
The CCTV footage at the three blast sites which was being scoured by police also did not reveal much,officials said,adding the role of the underworld was also being probed.
Officials said the forensic experts of National Investigation Agency(NIA) were satisfied with the nature of evidence collected from the blast sites.
Singh said investigations into the serial blasts in the metropolis was going on and several people were being questioned based on their “previous known linkages”.
