New Delhi, Jan 22 (ANI): The Delhi Police have registered an FIR against the Aam Aadmi Party protesters who staged a 33-hour demonstration near Rail Bhavan in New Delhi. The protest was led by Delhi CM Arvind Kejriwal, who on Tuesday called it off after the two SHOs of Malviya Nagar and Pahar Ganj proceeded on leave. Kejriwal and AAP members launched the sit-in protest on January 20 after the central government rejected their demand to suspend police officers for dereliction of duties in an alleged drugs and sex racket case. Delhi Law Minister Somnath Bharti had got involved in a public spat with the cops at Khirki extension over the case.
