Rashed Khan, general secretary of the party, said Nur was released around 4:30 pm.
Although Nur has been discharged he will not be able to speak to the media and is scheduled to be admitted to another hospital for further treatment, he said.
Nur was admitted to DMCH on August 29 with multiple injuries after a clash between activists of his party and Jatiya Party in front of his party office.
He was initially treated at the One-Stop Emergency Centre (OSEC) before being transferred to the Intensive Care Unit (ICU). Once his condition stabilised, he was moved out of the ICU, reports UNB.
He was given treatment under a six-member medical board.
