In the statement, Chidambaram said the investigators had arrived at the conclusion that there was no conspiracy to kill Karkare on the basis of three eye-witnesses, including Ajmal Amir, the terrorist who was involved in the attack and was apprehended from the scene of the crime.

Other two eye-witnesses were Arun Jadhav, a police naik who was also travelling along with Karkare and two other officers in the Qualis vehicle, and Maruti Madhavrao Phad, the driver of a government vehicle provided for the use of Maharashtra Principal Secretary (Health), he said.

"The investigators have reconstructed the sequence of events by talking to a number of people including police officers and policemen who were present at different locations," the Home Minister said citing report from Maharashtra government.

"The investigators have reached the conclusion that Shri Karkare took the most convenient route from his residence at Dadar (East) to the CST Railway Station and after conferring with the police officers at the Railway Station, decided to proceed to Cama Hospital," he said.
