Environmentalists from across the city have decided to stop working for the migrants after activist Afroz Shah, know for his Versova Beach clean-up initiative, tweeted on Tuesday night alleging that the Tilak Nagar cops harassed him for doing the same.

Shah in his tweet said, "Harassed for 2 hours by Tilak Nagar police. Taken to the police station. Let off by saying please leave. Suspending all my activities to help the poorest of the poor. Sorry migrants — the system doesn't allow me to work for you. Broken heart. Broken soul. I cry and I am in pain."
