The area around Aastha Kunj Park in Delhi, where a 17-year-old girl was allegedly gang-raped on Monday, September 21, 2026, had already been identified in Delhi Police dark-spot surveys, which are meant to find poorly lit areas. The park and surrounding stretches were among places where police flagged inadequate illumination to civic agencies. The surveys are conducted regularly, and police write to the relevant agency seeking repairs or installation of streetlights. Despite this, the lighting gaps remained when the alleged assault took place on Monday evening. Data shows that of the total 1,525 streetlights recorded across the southeast district, 33% were non-functional.
