Bengal Congress leader Koustav Bagchi arrested over his controversial remark on Mamata Banerjee

Police officials reached Koustav's residence at around 2:30 am and he was arrested in the morning.

He was taken to the Burtolla Police Station in north Kolkata.

Koustav has been arrested on the charges of criminal conspiracy, sexual harassment, intentional insult with intent to provoke breach of the peace, act induces or is likely to induce any person to commit offence against state or against public tranquility, word, gesture or act intended to insult the modesty of a woman, punishment for criminal intimidation and wantonly giving provocation with intent to cause riot, reports said.

On being arrested, Koustav said, "There is no rule of law in West Bengal but the ruler's law."

In reply to Banerjee's personal attack on state Congress president Adhir Ranjan Chowdhry, Koustav on Friday held a press conference and spoke on a book based on the Chief Minister's personal life.

Banerjee on Thursday launched a scathing attack on Chowdhury referring to his late daughter and driver in her response to the Trinamool Congress' debacle in Sagardighi assembly by-election.

When she was asked about Chowdhury's claim that the minority votes are moving away from the Trinamool, Banerjee said, "I won't answer. Let the minority people answer that. Why was Bogtui an issue in the Sagardighi bypoll?"

"He (Adhir Ranjan Chowdhury) is saying so many things but can he answer on his daughter's suicide, driver's murder? I know a lot of things. Don't trigger me to speak out," the Chief Minister said.

In reply, Chowdhury told a local news channel, "The Chief Minister has every right to talk about it. But will she have the patience to listen to my answers?"
