During police investigation, the role of the third woman, who is absconding, also came to light.
Meanwhile, Monserratte was taken for a medical examination to Goa Medical College at around midnight.
Police sources said that the MLA and the girl's mother were kept in different lock-ups in the Crime Branch headquarters located at Ribander, near here.
The police would seek his remand in a court today.
A senior police official yesterday said that police had examined ten witnesses and also recorded the girl's statement before a magistrate.
According to the girl's complaint, her mother and another woman hatched a conspiracy and sold her for Rs 50 lakh to Monserratte in March this year for sexual exploitation.
"Monserratte kept her in confinement, administered some stupefying substance and had sexual intercourse with her several times without her consent," it alleged.
"I have not done anything wrong. The complaint is totally false and bogus. This is just to frame me," he had told reporters yesterday before entering the Crime Branch office.
