The interviews took place in Lahore, Pak on 5 and 6 April. The purpose of these interviews was to seek specific information and the ACSU has confirmed that this information was provided by the players.
It was clarified that these interviews were not conducted in relation to any alleged breach of the ICC Code of Conduct.
As a matter of policy, the ICC does not comment on the specific details of the ACSU's investigations.
A source close to players said the ICC's ACSU questioned the players about an Indian man and his connection with the Pakistan team.
"(It was about) some gifts he gave them on the recent tour and his background, and how they had come to know him," the source said.
"He also showed them photographs of the gentleman with some people listed as bookmakers by the ACSU. But the players made it clear to them he had never made any offers to them, nor discussed any match details with them."
Under the ICC code of conduct, a player who fails to report an approach to fix games or underperform to his captain, team manager, board or ACSU can be banned for up to five years.
