Border Security Force (BSF) personnel raided three villages near the India-Bangladesh border in West Bengal's Malda district on Wednesday and picked up 20 people after some ammunition and important documents went missing from a border outpost.
The ammunition went missing from the Kumarpur border outpost, around 320 km from Kolkata on Tuesday.
The villagers alleged that BSF men entered the houses, breaking open doors and windows, and beat up women and children.
Many people from Kumarpur, Gobindapur and Moslempur villages fled their homes during the raid after BSF men allegedly forced a cleric of a local mosque to make an announcement over the microphone, asking villagers to return the stolen materials.
BSF officials have refused to comment on the incident.
Jabbar Sheikh, a panchayat member, told reporters that BSF personnel have recovered 40 rounds of live cartridges and some other materials, which were found lying in a mango orchard.
"We have informed the local legislator Krishnendu Choudhury," he added.
