The BJP today criticised West Bengal Chief Minister Mamata Banerjee for allegedly threatening Union Home Minister Amit Shah, who is on a visit to the state. Addressing a press conference at Bhubaneswar, BJP national spokesperson Sambit Patra alleged that Ms Banerjee, while addressing a public meeting in Bankura district in West Bengal, threatened the Union Home Minister. Mr Patra said, it is not only a threat to the Union Home Minister, but to the entire population of the country. He alleged Ms Banerjee has been running a dictatorship in the state. He also alleged that around 300 BJP activists were killed by TMC activists in West Bengal, while three thousand others had to flee their homes. He said there have been attacks on democracy in Bengal and the state is now destroyed by Ms Banerjee.
