He said the BJP candidate had taken permission to organise a meeting at Abholi block between 11 am and 5 pm.
However, Gadkari's chopper landed at 5.30 pm and the former BJP chief was stopped from proceeding to the venue of the meeting by police.
But, the BJP leaders forcibly made their way to the dais and held an election meeting for half-an-hour, Tripathi said.
District Returning Officer Ranveer Prasad said a thorough probe into the matter was on.
