Loud music played through speakers inside Sanjay Gandhi National Park (SGNP) during a marathon on Sunday morning, triggered criticism on social media over noise pollution in the eco-sensitive zone. The park authorities subsequently fined the organisers Rs 5000 and registered an offence for violating the conditions under which the event was permitted. A 16-second video of the music that apparently lasted little less than four minutes surfaced on social media, with users questioning how such a sound setup was allowed inside the protected area.
