West Bengal Chief Minister Buddhadeb Bhattacherjee slammed the Railways for not naming the Maoists in the FIR lodged for the Rajdhani Express hijack drama on October 27 and alleged that Trinamool Congress was in cahoots with Naxals in an attempt to dislodge the Left Front government.

"The CRPF named the Maoists and the group backed by it in the FIR. Why not the Railways? It is ridiculous that the Railways have said that they did not know who did it," Bhattacharjee told a Left Front rally in Kolkata.

"Chhatradhar Mahato's outfit PCPA, which is a creation of the Maoists held up the Rajdhani, but the names of the outfit did not figure in the Railways FIR," he said without naming Railway Minister and Trinamool Congress Chief Mamata Banerjee.

The Railways, he alleged, were trying to shield the Maoists and the group backed by them. "The Trinamool Congress is working with the Maoists to finish the Left Front. They think that they would be able to dislodge the Left Front government by joining hands with Maoists. We will unmask the Trinamool and the Maoist. We take up the challenge," he said.
