Alemao was the state PWD minister in 2010 when a US company officials reportedly paid bribe to an Indian minister.
"We had asked him (Alemoa) a set of questions during the investigation yesterday. We are continuing to ask him the questions," a senior crime branch official said.
Alemao's statements are crucial ahead of the questioning of former Goa CM Digambar Kamat who is scheduled to appear before the Crime Branch this afternoon.
Both Kamat and Alemao have refuted charges of having accepted any bribe in connection with this case.
