The support for 22-year-old climate activist Disha Ravi - arrested last week in the 'toolkit' case - is growing in her alma mater, Bengaluru's Mount Carmel College. A letter of solidarity that also condemns her arrest now has 900 signatories, up from 300 yesterday. On Wednesday, NDTV met with two women - Dr Swati Shivanand and Aishwarya Ravi Kumar - who had initiated the letter to drum up support for the activist.
