He also lashed out at CPI(M) leader Sujan Chakraborty, alleging that the Left Front is trying to stall the recruitment of teachers. “We are fighting against communal forces and they (CPI-M) are joining hands with these forces,” he maintained. The police on Sunday interrogated Urdu teacher Mohammad Sanaullah, who had faced agitation while he went to join the school on Thursday. He is a resident of Kidderpore in Kolkata and has been staying near the school for the last sixteen days. Senior Trinamool Congress leader Gulam Rabbani and Islampur MLA Kanailal Agarwal visited the residences of the two deceased students on Sunday. It may be mentioned that Trinamool Congress supremo Mamata Banerjee, who is currently on an official tour of Europe, had said on Thursday that BJP and RSS have to answer why the two students were killed.
