A livid Vadra was seen on a video footage shown on TV channels asking the reporter four times as to whether he was serious about his land deal question.
Vadra had earlier anwsered a couple of questions posed by a reporter inside Ashoka Hotel.
"I mean, Are you serious Are you serious Are you serious Are you serious," Vadra kept asking repeatedly, as he lost his temper and stared into the eyes of the reporter and shoved the microphone away.
The reporter was seeking Vadra's reaction to the decision of the new BJP government in Haryana to investigate all land deals whether it involves Vadra or the former Chief Chief Minister Bhupinder Singh Hooda or anyone else.
Vadra was also heard saying, "put your camera off".
"Are you nuts. What is wrong with you" he said from a distance as he was led away by his security guards.
At this stage, the reporter was heard saying that his question was legitimate.
To this, Vadra responded asking whether the reporter was the right person to whom the questions on the land deals should be anwsered.
A TV channel quoted a statement released by Vadra's office as saying, "It was a private event and media was not supposed to be there, thought it was a private internal reporter asking questions, not ANI."
