Dr Shamil Uddin Shimul, a leader of the pro-Awami League Swadhinata Chikitshak Parishad, was released from the Rajshahi Central Jail around 4.45pm on Sunday, said jailor Ismail Hossain.
Rajshahi Metropolitan Magistrate Sharmin Sultana had granted him bail earlier in the day.
He was allowed to step out of the prison after the authorities got a copy of the court order, Hossain said.
