Madhya Pradesh Home Minister Bhupendra Singh on Saturday said the attack on the "Rath" (campaign vehicle) of Chief Minister Shivraj Singh Chouhan during his "Jan Ashirwad Yatra" was part of a conspiracy to kill him. Talking to mediapersons here, the Home Minister said: "Stones were thrown at the vehicle of the Chief Minister in a pre-planned manner. The stones hit the glasses of bus, which could have hit him (Chouhan) as well.

"It was clearly a pre-planned attack on the life of the Chief Minister but alert security personnel thwarted the attempt." Three persons have been arrested in connection with the attack, he added. On the other hand, the Congress has said that the incident was a result of intelligence failure and therefore, the Home Minister should resign.
