A Bharatiya Janata Party (BJP) worker, named Saraswati Das, was allegedly shot dead by miscreants in Basirhat in West Bengal's North 24 Parganas district.
The BJP had claimed that Ms Das, who was a housewife, was killed by Trinamool Congress (TMC) goons.
"Saraswati Das, BJP worker was brutally shot dead by TMC goons in Basirhat. Law and order has totally collapsed in West Bengal where no one is safe. Mamata Banerjee is also Home Minister of West Bengal," read a post on the official Twitter handle of BJP''s West Bengal unit.
Ms Das had played an active role for the BJP in the recently concluded Lok Sabha elections.
