In preparation for the G20 summit on September 9-10, the Delhi police reported instances of pro-Khalistan graffiti defacing walls at multiple metro stations. These slogans, including 'Delhi Banega Khalistan' and 'Khalistan Referendum Zindabad,' were found spray-painted in black across stations like Punjabi Bagh, Shivaji Park, Madipur, Paschim Vihar, Udyog Nagar, and Maharaja Surajmal Stadium, all located in west Delhi. The Delhi Police identified members of the banned group Sikhs for Justice (SFJ) at various stations, such as Shivaji Park and Punjabi Bagh, where they were actively writing these Khalistan-promoting slogans. Additionally, anti-India graffiti was discovered on a wall at Government Sarvodaya Bal Vidyalaya in Nangloi. Responding actively, the Delhi Police's Special Cell deployed personnel to various sites, while the DCP (metro) confirmed the removal of all graffiti from metro station walls. Investigations are ongoing, with a focus on analyzing CCTV footage to swiftly identify and apprehend suspects.
