A Canadian university student arrested on suspicion of having links to a deadly cafe attack in the Bangladeshi capital in July has been cleared of the charges, police said on Wednesday.
A court in Dhaka cleared Tahmid Hasib Khan, a student of Toronto University, after a request by investigators for the charges to be dropped, officer Humayun Kabir told reporters.
Khan had been released on bail on Sunday as there was no evidence to link him to the attack.
Khan and a private university teacher, Hasnat Karim, were arrested on August 3 on suspicion of being involved in the attack. Karim remains in jail.
Both men were in the Holey Artisan Bakery when Islamist militants entered the eatery and took hostages on July 1. Nine Italians, seven Japanese, two Bangladeshis, one Indian and one Bangladesh-born US citizen were killed.
Five militants, a chef who was believed to be an associate of the attackers, and two police officers were also killed during a commando operation.
Police have killed at least 14 suspected militants, including a Bangladeshi-born Canadian man, in the last three months as part of counter-terrorism raids launched after the cafe attack.
