Karnataka Home Minister G Parameshwara on Saturday said the police are conducting in-depth investigation into the bomb blast at the Rameshwaram Cafe and are looking into all angles.
He said investigators have gathered certain information from CCTV footage, adding that the footage from Bengaluru's public transport buses is also being analysed as part of the probe to nab the culprit.
A meeting of senior Home Department officials with Chief Minister Siddaramaiah has been convened on Saturday.
A detailed discussion will be held at the meeting following the Friday's incident at the quick-service eatery in Brookefield area in information technology corridor in east Bengaluru, that left 10 people injured, and the government will give certain instructions to the officials.
"Several teams have been formed to investigate. In depth investigation is going on with seriousness, some traces have been found. Some information has been gathered from CCTV footage. At that time on that route number 26 buses had gone. There is information that he (suspect) has come by bus. So, (route number) 26 buses have been verified at Bangalore Metropolitan Transport Corporation (BMTC)," Parameshwara said.
Addressing reporters in Bengaluru, he said, 'on the basis of the theory of elimination', more buses are being verified for footage, as BMTC buses have cameras.
"We expect information from it. Gathering all this information we will nab the culprit. At no cost we will let go. No matter how much they try to escape, we will not leave them," he added.
At this moment it is not possible to say whether any organisation or an individual was involved, the home minister said.
There were certain theories during his visit to the cafe on Friday night, expressing suspicion that someone might have done it out of 'heartburn', unable to digest the cafe's success and expansion.
"We will look into all angles. Whichever angle it might be, we will verify them and catch the culprits behind the blast," he said.
Asked whether the probe will be handed over to central agencies, Parameshwara said, "We have efficient officers, we have efficient FSLs (Forensic Science Laboratory). We are advanced. FSL team has collected samples, they have gathered information on timer fixed, the capacity of the explosive. It will help the investigation."
Responding to opposition Bharatiya Janata Party's demand that he quit by accusing him of failing in maintenance of law and order, the home minister said, seeking resignation has become a practice for them, they seek resignation of chief minister and home minister for 'everything'.
"They keep seeking resignation. When the cooker blast occurred in 2022 (Mangaluru) did they resign then? We have a responsibility to run the administration, we will not let anyone escape," he said, noting that he had appealed to the opposition not to do politics on the issue and to cooperate, as it is the matter of Bengaluru and state's pride and security of the people.
Listing out various measures taken by his department for 'safe' Bengaluru recently, Parameshwara said patrolling has been increased, artificial intelligence is being used, and about 7,500 cameras have been installed at various places.
"In this incident too footage from CCTV cameras installed have been gathered, all those things are being verified. It will help," he said.
On whether there was any link to the incident with 'Pakistan zindabad' slogan that was allegedly raised in the corridors of 'Vidhana Soudha' recently after Rajya Sabha polls results were declared, the minister said, "We can't say like that. I don't know. I cannot speculate."
