But not only Bihar, it was the first time in the history of the country that the House  Police was called inside, SP and DM were working to beat and drag out the legislators themselves. The female MLA Anita Devi, who also comes from a backward society, was dragged off her hair, opened a sari and dragged away. Today is the day. ‘  The people of the country will remember this as “black day”.
 Many videos are also going viral on social media, in which the police and administration people can be seen inside the house beating the MLAs with kick and punches.
