Centre trying to prevent truth behind Odisha train crash from coming out: Mamata Banerjee

West Bengal chief minister Mamata Banerjee on Wednesday hit out at the BJP-ruled Centre alleging that there were attempts to suppress the cause of the train accident in Odisha. The Central Bureau of Investigation (CBI) was engaged to probe into the June 2 triple train crash but pieces of evidence have already been removed, Mamata claimed.
