Representatives of the Ceylon Thowheed Jamaath organization will testify before the Parliamentary Select Committee probing the Easter Sunday explosions.
It's founder Andul Razik will also be among those who will testify before the committee on behalf of the organization.
After the Easter Sunday explosions, the Ceylon Thowjheed Jamaath distanced itself from the National Thowheed Jamaath and its founder Zaharan Hashim.
However, Bodu Bala Sena General Secretary Galagodaaththe Gnanasara Thera called for the arrest of the members of Ceylon Thowheed Jamaath describing them as "extremist militants" at core.
The Police have maintained that they have not found evidence to arrest members of the Ceylon Thowheed Jamaath and its leader Razzik.
