Internet and data services have been suspended in Agartala on 21 September, following the killing of a journalist, who was covering a clash between two political parties in Mandwai of West Tripura.
A journalist Santanu Bhowmik was hacked to death on 20 September, while covering the clashes between Indigenous Peoples Front of Tripura (IPFT) and Tripura Upajati Gan Mukti Parishad (TUGMP), tribal wing of Communist Party of India (Marxist) CPIM.
