Four low-intensity blasts had disrupted life on J M Road on August 1.u00a0“Much of the CCTV footage, which has been collected from various shops and hotels after the four low-intensity blasts took place on J M Road, is of no use as the resolution of the CCTV cameras was poor and because of this the investigators are finding it difficult to investigate further,” Commissioner of Police Gulabrao Pol said.
