The Centre has expressed deep concern over the continuing violence in Bengal even after the national elections and issued an advisory to Mamata Banerjee's government, sources said. The state BJP had approached home minister Amit Shah, claiming three of its workers were killed by Trinamool Congress workers in the North 24 Parganas. This was the third instance of violence in the last 10 days, in which one Trinamool worker was also killed.
