There have been disputes over match-fixing among seniors like Arjuna Ranatunga and Kumar Sangakkara.
The FCID investigations have reached a decisive juncture, with several persons to be questioned, the official said.
Among them is a key member of the 1996 world cup winning team.
Furthermore, information will be obtained from Arjuna Ranatunga, Kumar Sangakkara, Aravinda de Silva and other seniors.
Attention has also been drawn to two leading businessmen involved in cricket betting too.
