On August 3, a CTTC team arrested Hasnat and Toronto University student Tahmid Hasib Khan, who is now in jail following his remand twice, from the city's Gulshan and Bashundhara areas respectively for their suspected link to the attack.
Abul Hasnat, a businessman, and Tahmid Hasib, a Bangladeshi origin Canadian, were rescued along with 11 others during a commando operation at the Holey Artisan Bakery at the city's diplomatic zone Gulshan on July 2 following a 12-hour hostage standoff.
Their family members claimed that they had remained traceless since then. However, law enforcement agencies said they set them free after interrogation over the café' attack.
Twenty hostages, including 17 foreign nationals, were killed by militants, while five militants and one suspected associate of the attackers were killed during the commando operation in the café.
