A CCTV camera at the entrance of a three-storey residential building at the site of the April 17 blast near the BJP office in Bangalore has captured images of the suspected bike bomber in the minutes before the explosion.
The footage shows a bald man arriving in front of the house,parking the motorcycle in between two cars and a policeman,and hurrying away.
The bomb on the TVS Suzuki Max 100 R goes off around six minutes later.
While the images are not clear enough to identify the suspect clearly,they strongly suggest that he was aware of the impending explosion,sources familiar with the investigation said. He comes into the cameras frame from the top of the street on which the BJP office is located at 10.22 am,and the explosion occurs at 10.28 am. The camera,hit by shock waves,went off soon afterward.
The owner of the new house had installed the camera to capture images of workers going in and out. It was active when the blast occurred,and it has captured images, a source said.
The footage has been handed over to police along with 31 days back-up images,the owner of the house said. Police were in the process of improving the images,and were confident of a breakthrough soon.
Investigations were,however,yet to zero in on the final user of the motorcycle on which the IED was planted,sources in the Bangalore Police and NIA said. Investigators have questioned the first buyer in whose name the vehicle was registered and three others who used it later in Tamil Nadu,the sources said. These individuals were tracked down from the chassis and engine numbers of the two-wheeler.
The motorcycle may have changed a dozen hands but finding the last user whether it was a buyer or a thief is important to track the people who planted the bomb, an investigator who has been assisting the NIA and Bangalore Police said.
