A prominent spice trader and father of two suicide bombers, Mohamed Yusuf Ibrahim, is in custody on suspicion of aiding and abetting suspects, Sri Lankan police spokesman Ruwan Gunasekera tells CNN.
Ibrahim is the founder of Colombo-based Ishana Exports, which describes itself on its website as the "largest exporter of spices from Sri Lanka since 2006."
Ruwan Gunasekera added that all other members of the Ibrahim family are believed to be detained.
Ibrahim was among dozens of people arrested in the wake of the attacks.
