WADA

Following the blast, a public meeting was held and a minister for the district of Wada promised that the local government would take action.

At a different cluster of makeshift plants in Wada, just outside Mumbai, a team from BBC Indian Languages saw soot, dying vegetation and polluted waterways around the sites.

At the site the BBC visited in Wada, two women and two children were killed in January when there was an explosion at one of the plants.

In what ended up being a "late night" on 14 February, Sinner's lawyer Jamie Singer was deep in phone calls with Wada's most senior lawyer.

Sinner and Wada announced they had "entered into a case resolution agreement" over his two failed drugs tests last March.
