Bengaluru Police commissioner M.N. Reddi on Wednesday informed the media that they have got the sketches from the people who were present on the street during the blast.
"The teams have been continuously working on various fronts and pursuance of various angles. They have also been able to get some sketches from people who were there on the street," said Reddi.
He, however, added that the police is not 100 percent sure whether those sketches are of the people whom they would like to publicize at this point in time.
"We need to corroborate and also make sure that the other evidence fits into that therefore we have not released any sketches which we hope to do as soon as possible," he added.
He also told the media that the CCTV footages are being very laboriously examined by the teams, but the footage has not been satisfactory because it is taken from various cameras with different angles and technologies.
He assured that the police is looking at the entire footage of the area and teams are going through that in detail, but so far nobody has been detained from the Karnataka region.
