Responding to a question on the action of Major Leetul Gogoi, he said the Army officer's action had helped polling officials and policemen escape unhurt.
The major allegedly tied the man to the bonnet of a jeep on the day of bypolls to the Srinagar parliamentary constituency on April 9, apparently in a bid to deter stone- pelters.
"I appreciate it and also support it," Shah told a press conference here on the completion of three years of the Modi government.
Major Gogoi was awarded the Chief of Army Staff Commendation Card.
Commenting on the prevailing situation in Jammu and Kashmir, Shah said Prime Minister Narendra Modi had been monitoring the situation minutely and the government would find a solution.
