Two police cases were registered against Trinamool Congress MLA Sonali Guha and her supporters for causing obstruction in discharge of duty and criminal intimidation, among other offences.

"We have filed two cases under Sections 353, 341 and 506 against Guha and her supporters Wednesday for locking at least 13 policemen including IC (inspector-in-charge) S Basu inside Nodakhali police station in South 24 Parganas on Tuesday night," a police officer said.

Ms. Guha had stormed into Nodhakhali thana that falls in her constituency with her supporters on Tuesday protesting against the partisan attitude of the local police.

This issue was raised in the West Bengal assembly.

"Guha has the right to protest against any unrighteous incidents in her area. But this is not the right way to protest. This is a dishonour to her position as a MLA. If the charges against her are proved right, necessary action will be taken against her," Assembly Speaker Hashim Abdul Halim told a TV channel.
