NEW DELHI, Sept. 30 -- Delhi Police on Tuesday filed a case against Aam Aadmi Party (AAP) leader Saurabh Bharadwaj, Tilak Nagar MLA Jarnail Singh and party worker Saheb Singh, slapped on Sunday by Public Works Department minister Parvesh Verma, for allegedly assaulting a head constable during demonstration in Tilak Nagar on Monday. They went to Tilak Nagar station over Sunday. A man in a green T-shirt, identified as a plainclothes head constable, walks ahead before being roughed up by AAP leaders. Camera loses them as it shakes. Police registered a case for assault and obstruction of duty on his complaint. It followed former chief minister Arvind Kejriwal's visit to Tilak Nagar demanding an FIR against Verma for allegedly slapping Saheb Singh, from Jarnail Singh's media team. Bharadwaj alleged official was "planted". "This man along with another few entered our crowd, behaved like goons and started hurling casteist abuses to our councillor. They were physically assaulting our people without any provocation. We handed them to police. We have all the videos. Does he look like a policeman?" he posted on X. He alleged men were "planted by police to create riot-like situation" and claimed conspiracy to create communal tensions. On Monday, Delhi Police had lodged a non-cognisable report (NCR) against Verma on charges of causing hurt for allegedly slapping Saheb Singh. Police also registered an FIR against Jarnail Singh based on a complaint by a PWD official, who alleged that the MLA had visited a roadwork site on September 24, tried to forcefully stop the work and "illegally demanded money". Sunday's incident took place while Verma was inspecting roadworks in Delhi's Vikaspuri. On Tuesday afternoon, Bharadwaj, Jarnail Singh and other AAP leaders and workers were detained briefly by police near Delhi Police headquarters, where they had gathered to demand an FIR against Verma. "The police only want to listen to BJP ministers and give them security. For us, there are only detentions," Bharadwaj said. In response, Delhi Bharatiya Janata Party (BJP) spokesperson Praveen Shankar Kapoor termed the protest Bharadwaj's attempt to "divert the attention of people" from Jarnail Singh's "questionable record"....
