The Congress on Wednesday slammed the Centre after police and security forces allegedly entered its party headquarters and picked up some party workers. Congress MP Karti P Chidambaram shared a video on Twitter where cops can be seen barging into the party office and carrying away a man, presumably a party worker, as a group of them raise slogans, question the police, and record the incident on their phones. Mr Chidambaram said the Delhi police were behaving like the "private militia" of the BJP.
