Lawmakers of Mamata Banerjee's Trinamool Congress spent the night at Assam's Silchar airport, after they were formally arrested late Thursday evening. The lawmakers had gone to the state to campaign against the draft citizens' list, which triggered a political storm, when they were stopped by the police. This morning, six of the eight lawmakers took a flight back to Kolkata. The other two members are expected to take a flight to Delhi later this afternoon.
