Meanwhile, the Election Commission (EC) has asked the Karnataka government, particularly the police, to take all possible measures to ensure that the May 5 polls are not disrupted. The EC said this in the wake of the blast outside the BJP headquarters here on Wednesday, which had left 16 people injured.
Deputy Election Commissioner Alok Shukla, in-charge of the assembly polls, said the Commission had received information that the blast was an act of terror, according to one report.
Karnataka Chief Minister Jagadish Shettar appealed to the media to maintain calm and not politicise the blast issue. He said the police were investigating the matter and were assisted by the central agencies. He said the details would be known soon.
The CM also said the government will take care of the loss of property caused in the blast and promised compensation.
The NIA and NSG were examining the blast site.
A national news channel had on Wednesday reported that the Karnataka police had got an alert from intelligence agencies about a potential attack in Bangalore ahead of the elections. Though it was reported later that the alert was a general one and did not specify the target of the attack.
Mumbai, Chennai and Gujarat were also kept on high alert in the wake of the Bangalore blasts.
