The party workers welcomed Congress General Secretary in-charge of Uttar Pradesh Priyanka Gandhi in Prayagraj on February 21.
She came at Prayagraj to support boatmen who were allegedly harassed by local police.
She visited Banswaar village in trans-Yamuna area of the district to meet members of fishermen community.
Priyanka had travelled in Sujit Nishad's boat after she took a holy dip at the Sangam, a confluence of the Ganga, Yamuna and mythical Sarswati River, on Mauni Amavasya where she had performed puja.
She had later posted a video where she was seen assisting Nishad in rowing the boat.
Nishad had informed Priyanka about issues that boatmen belonging to the Nishad community were facing, including brutality against them by police whom he alleged had destroyed their boats.
The boatman requested her assistance in raising their voices against the oppression to which she agreed, party sources said.
