An MLA from the ruling CPM in Tripura has been caught on camera threatening policemen while demanding the release of two of his party workers. Shankar Prasad Datta barged into an East Agartala police station on Wednesday afternoon and entered into an argument with the officer-in-charge of the police station. Mr Datta was later captured by cameras misbehaving with the cop and even forced the latter to free the two party activists who had been detained in a case related to firing in a busy market area earlier in the week.
