Mysuru/Tumakuru, 1 Mar

Karnataka Chief Minister Siddaramaiah on Thursday said investigations are on to ascertain the cause and nature of the explosion at popular eatery Rameshwaram Cafe in Bengaluru on Friday, and added that it might have been caused by an "improvised explosive device".

He said those involved will be found and strict action will be taken against them. "According to the information I have got, after 12 PM someone placed a bag and went. Investigations are going on, Siddaramaiah said, adding that all the injured persons are out of danger.

Speaking to reporters in Mysuru, he said, "CCTV and other things are being examined. We have come to know about someone placing a bag. It is said to be an improvised explosive blast. We have to see, the investigations are on."

Asked whether it was a terrorist act, the CM said, it is not known and investigations are on. Police are at the spot and he has asked the Home Minister also to visit the spot. "It was not a large-scale blast, it was an improvised explosive blast. Such things have happened earlier too, it should not happen. Let's see what it is. In recent times such blasts had not taken place other than the incident in Mangaluru during BJP rule. This is the first such incident during our government," he added.

Stating that the incident should not be politicised and everyone should cooperate, Siddaramaiah said strict action would be taken against those involved.

Asked if any high-level inquiry will be ordered, he said, "Let the things become clear. As of now we have information that the blast has taken place." "I have spoken to the police, they told me about the ongoing investigation. There was a small bag carried by a person. The identity of the person is not known. The cashier at the eatery is being questioned, as the person had gone to the cashier to take the token and ate the food...the same person had placed the bag," he added.
