A group of people allegedly attacked the houses of seven families of BJP supporters at Dakshin Goalpara village on the outskirts of Raiganj town on Wednesday night, assaulted family members and took away valuables.

Three persons, including a woman, who suffered serious injuries, were admitted to Raiganj Government Medical College and Hospital. Police started a probe and arrested one person.

The targeted families have accused a local Trinamul leader of orchestrating the attack. Trinamul leaders, however, denied the charges and said those families had indulged in illegal activities and faced spontaneous protests by villagers.

“All of us are BJP supporters. For past few days, Bappa Adhikary, a local Trinamul leader, had been mounting pressure on us to defect to Trinamul. A few days back, they beat up a woman supporter. On Wednesday night, they organised an attack on us,” alleged Usha Roy, a member of one of the seven families.

The attackers, she said, barged into their houses, damaged the furniture, beat up every family member and left with valuables. “We have been threatened with dire consequences if we do not listen to them,” she added.

BJP supporters Rina Roy, Badal Roy and Bijoy Roy are hospitalised at the RGMCH.

A police team from Raiganj reached Dakshin Goalpara and arrested a person who locals said is a Trinamul supporter. Police confirmed the arrest but did not specify the political leanings of the person.

Bappa Adhikary, accused of the attack, brushed aside the charges. “These families were running illegal hooch dens and selling drugs too. Other villagers were aggrieved with them for their activities. On Wednesday night, some villagers ransacked their homes. It was a spontaneous outburst of people,” he said.

“Our party has nothing to do with the incident,” Adhikary said.
