Along with Vaman Sardesai, whom she later married, she ran an underground radio station, Voice of Freedom, that transmitted across Portuguese Goa from 1955 to 1961, advocating the cause of the Goan independence movement.

[3][4][5] Libia Lobo, known by the nickname of "Libby",[6] was born on 25 May 1924 to a Catholic family[7] in Porvorim, Bardez taluka, Portuguese Goa.

[10][11] In 1954-55, the Portuguese attacked and killed several Satyagrahis who had peacefully entered the Goan borders, demanding the end of colonial rule in Goa.

Following this, India closed its borders with Goa, imposing an economic blockade, thus reducing free movement and trade.

Lobo, Vaman Sardesai and Nicolau Menezes, a Goan independence activist who had been living in hiding in Bombay, came together to form a team.

This became the Voice of Freedom radio station, through which Lobo, Sardesai and Menezes would transmit news and important information to Goans.

On December 17, 1961, the station transmitted a direct message from then Defence Minister of India, V. K. Krishna Menon, requesting the Portuguese Governor General to surrender.

[10] Following the Liberation of Goa, Lobo joined the Ministry of External Affairs to help in their efforts to repatriate the captured Portuguese troops.
