This came after the central agency conducted raids at 13 locations in four districts of West Bengal on February 19. The central agency team served the notice to his wife Rujira Banerjee to join the inquiry. “At 2 pm today, the CBI served a notice in the name of my wife,” Abhishek Banerjee tweeted. “We have full faith in the law of the land. However, if they think they can use these ploys to intimidate us, they are mistaken. We are not the ones who would ever be cowed down.”
