Bengaluru: As investigators zeroed in on some terror groups, sketches of suspects have been drawn in connection with the explosion outside a restaurant here that killed a woman and injured three others.
"We have zeroed in on some (terror) groups - and have drawn sketches of some people belonging to these outfits. We are in a process of verification and confirmation - whether these sketches match the suspects who were involved in the explosion," Additional Commissioner of Police (Law and Order) Alok Kumar told PTI.
The blast triggered by an Improvised Explosive Device placed in a potted plant had occurred outside the restaurant on Church Street in the city's central business district on Sunday last claiming the life of 38-year-old Bhavani who was on a visit to city from Chennai.
Asked when the sketches would be released, Bengaluru Police Commissioner M N Reddi replied, "Not today."
Earlier, Kumar said police were interacting with various agencies and other state police officials.
"We are interacting with various agencies which have come here, and at the same time we are in contact with other state police forces also. We are trying to have a conclusive link," he said.
Asked if any specific request was being made by police to National Investigation Agency or other agencies, Kumar who is also heading the Special Investigation Team (SIT) to probe the blast said, "No we have not made any specific request. We had meeting yesterday with them (NIA)."
"If there is anything they can share with us or that is required, on the need basis that will be done,?" he added.
On reports that a person has been held in Bihar, Kumar said "we are not aware of that thing and we have not been informed about that arrest."
