The CBI on Monday launched parallel raids and later arrested TMC heavyweights and ministers Firhad Hakim, Subrata Mukherjee and MLA Madan Mitra in its probe on the Narada sting case. Within hours, Chief Minister Mamata Banerjee reached the CBI office.

According to the TMC lawyer, CM Mamata Banerjee has challenged the CBI to arrest her as well while calling the detention of her ministers 'illegal'. Mamata Banerjee has said she will not budge from the CBI office if she is not arrested along with her ministers.
