After they were returned to Angola, João Mancoca found himself in Luanda. Mancoca, along with Sala Filemon and Carlos Agostinho Cadi, urged the others in their group to adhere to the Bible and to reject practices that were not in harmony with it. Later, when Toco was being relocated to a place in the south, he passed through Luanda. It was obvious that he had become even more strongly influenced by the beliefs of the followers of Kimbangu.

In 1952, as a result of treachery on the part of one who was associated with their group, João Mancoca, Carlos Agostinho Cadi, and Sala Filemon were arrested and banished to Baía dos Tigres, a penal colony associated with a fishing station.
