An announcement regarding the immersion of Ganpati idols in the Dahisar river at Sanjay Gandhi National Park (SGNP) has raised the hackles of nature lovers.

On September 6, local Shiv Sena leader Bhaskar Khursange, a former corporator, tweeted that he had written to the SGNP field director, requesting permission for Sarvajanik Ganesh Mandals from Borivli, Dahisar and Kandivli to immerse idols in the river inside the SGNP. Political posters announcing immersion activities were also put up outside the park early on Wednesday.
