KOLKATA: Trinamool Congress leader Saifuddin Khan was killed after assailants fired and threw bombs at his car last week. At least three people were killed, including a driver and a passerby. The car belonged to party MLA Biswanath Das. The West Bengal Police's Criminal Investigation Department has taken over the investigation into the matter. The MLA has claimed that the attack was targeting him. “I was the target, but because I got off at the party office I had a lucky escape.” Das had been dropped off at the local party office just minutes before the attack. He said the attack was planned and carried out by members of the Communist Party of India (Marxist) and the Socialist Unity Centre of India (Communist). However, both parties have denied any involvement and alleged that the attack is another incident of an internal feud within the party.
