He had been imprisoned at his farmhouse near the capitall that prison officials had designated a 'sub-jail," Geo TV News reported.
A judge granted bail to Musharraf Monday.
As part of his release, Musharraf will be on the Interior Ministry's exit control list, meaning he's not allowed to leave the country before his trial.
Musharraf is accused of ordering a crackdown on the pro-Taliban Red Mosque in Islamabad, in which imam Abdul Rashid Ghazi and his mother, Sahib Khatoon, were among the victims.
He was on self-imposed exile but returned earlier this year. He was banned from running in the general election and put under house arrest in April for a series of charges stemming from his time in power between 1999 and 2008, the BBC said.
He is accused of ordering the assassination of former Prime Minister Benazir Bhutto and Baloch tribal leader Nawab Akbar Bugti, and is also charged with attempting to fire the higher judiciary in 2007, the BBC said.
