Home Minister P Chidambaram today hinted at displeasure over the delay in making a breakthrough in the investigations into July 13 Mumbai blasts, saying a view will soon be taken on what to do with the probe.
Chidambaram said there were several leads but no conclusive evidence against any accused.
"We would have to take a view on what we would do with Mumbai investigations. Since July 13, it is now quite a lot of time. We are concerned," he said at a press conference when asked about the progress of probe into the multiple blasts in the metropolis.
The minister said he had not spoken to Maharashtra Chief Minister Prthiviraj Chavan in the last few days but would talk to him soon on the issue.
"Let me talk to the Chief Minister and get back," he said.
The Maharashtra ATS and the Mumbai Police Crime Branch are probing the case.
Twenty-four people were killed when bombs exploded in three places in Mumbai on July 13, 2011.
The National Investigation Agency may take over the probe, sources said.
