A man named Shaukat Khan Pathan, who was associated with Don Karim Lala’s gang of Pathans, started exploiting her financially and physically. Gangubai approached
Karim Lala, a prominent underworld don of that era, to lodge a complaint against Pathan. Lala assured her of help, and in return, she tied a rakhi (a sacred thread symbolising brotherhood and protection) on his wrist. Following this, Lala personally warned and roughed up Shaukat Khan. As a result, Gangubai gained the protection of the underworld and earned widespread respect in Kamathipura. Since then, Gangubai's repute as Karim Lala's supposed sister grew during the 1960s. St. Anthony's Girls' High School, which was established in Kamathipura in 1922, started a campaign to clean up the area from bad influence. This led to an order to move the
brothel. Gangubai vehemently opposed this and allegedly presented her case to the then Prime Minister
Jawaharlal Nehru i.e. in 1957, and as a result, the brothel was not moved. During this time Gangubai was also working for various issues of orphans and women in the prostitution business. It has been noted that Gangubai defended the rights of the brothel's sex workers by insisting on a weekly Sunday break, during which they were not required to take clients, and by encouraging them to spend their time off in public spaces without being shamed. Gangubai also reportedly counselled and sent back many young women, who had fled their homes to work in films but were forcefully brought into prostitution. For this reason, everyone used to respectfully call her
Gangubai Ganga Maa. After her death, her photographs and statues were erected in brothels of the area. == In popular culture ==
