Youth Congress President Srinivas BV on Monday tweeted that Priyanka Gandhi has been arrested by UP Police from Hargaon village in Lakhimpur Kheri district.
The Congress general secretary reached Lakhimpur early on Monday a day after violence during a farmers' protest claimed 8 lives, including four farmers.
The Congress leaders alleged they were not allowed to meet the victims of the violence.
Priyanka Gandhi, who is accompanied by party leader Deepender Singh Hooda among others, had to take alternative routes to reach the destination as heavy security was deployed on the main roads amid tension in the violence-hit region.
