Kolkata: The Trinamool Congress is gearing up to observe a two-day ‘Black Day’ across West Bengal to protest the detention of its members at Silchar airport in Assam.

TMC leaders said that the members of the Trinamool Congress delegation were treated like “infiltrators” by the BJP government in the north-eastern State.

However, the BJP has a completely different picture to present. Three cops were allegedly assaulted by TMC leader, MLA Mohua Moitra, after the delegation was prevented from violating Section 144 of CrPC imposed in Silchar while they were going out of the Kumbhirgram airport.

BJP MP Babul Supriyo told MyNation that the lady police personnel requested  Moitra to calm down, but the TMC members assaulted the cops.

Assam DGP Kuladhar Saikia said that two cases had been registered against the TMC MPs and MLAs.

TMC party yesterday blocked rail and road traffic in Kolkata and its suburban areas to protest the detention.

The party head and West Bengal Chief Minister Mamata Banerjee said, "The delegation was full of respectable members. The police atrocity is condemnable. This shows their (BJP) frustration. This is the beginning of their end".

The TMC and BJP are at loggerheads over the National Register of Citizens (NRC), which has kept 40 lakh people out of the list.

Banerjee said that the BJP was trying to divide and rule the country and had plans to throw Bengalis and Biharis out of Assam.

"The BJP has the audacity to say that they would implement NRC in Bengal and it thinks only they and their supporters would stay in India and the rest will have to leave the country," said Banerjee.

In July, BJP president Amit Shah said that no Indian should be worried about the NRC. He pointed out the opposition was politicising this issue for vote-bank politics and asked them to clarify their stand on the Bangladeshi infiltrators.

Shah is expected to address a massive rally in the heart of Kolkata on August 11. State BJP in charge Kailash Vijayvargiya, national secretary Rahul Sinha and key face of BJP in the state Mukul Roy plan to up the ante in Bengal.
