The parliamentarians include PPP Chief Whip Gail Teixeira, Nigel Dharamlall and Irfaan Ali.
While only the three have been interrogated thus far, others are expected to appear before investigators of the Special and Organised Crimes Unit (SOCU).
Teixiera on Wednesday told reporters at a press conference that the officers came to her home and requested an audience with her.
"Knowing that some of the other people had appointments, I said okay can I come in today or tomorrow and they said today so I went in," the Chief Whip detailed.
She stated that she went to SOCU in the company of her attorney Bibi Shaddick.
Asked what she was questioned about, Teixeira said she could not"talk about those right now" but noted that the questions were centered around the audit report submitted by Anand Goolsarran.
Goolsarran has said that his report has found numerous damning pieces of evidence that shows how NICIL, the government’s holding company for state assets, was being run.
