The incident happened on Sunday when a party leader, considered as a supporter of state Health Minister TS Singh Deo, was allegedly stopped and heckled while he was delivering a speech.

The former Uttarakhand chief minister insisted on going to Lakhimpur Kheri with his convoy and was stopped at the Baheri toll plaza, the border of Bareilly district and Uttarakhand, the SP said.
His remarks came hours after Congress leader Randeep Singh Surjewala claimed that it was 78 party legislators, not Sonia Gandhi, who sought Singh's ouster in a letter to the central leadership.
The former chief minister said the only pressure he had been under for the past few months was that of his own loyalty to the Congress, because of which he continued to tolerate insult after insult.
Alleging that the former Punjab chief minister was playing into the hands of people with whom he had no ideological ties, Rawat said Singh should have stood with the Congress leadership.
Congress spokesperson Supriya Shrinate said that Rawat is closely monitoring the situation and is completely aware of all the happenings.
