However, he was arrested again yesterday on the charge of involvement in the killing of the Lal Masjid cleric.
Musharraf, who was then army chief and President, had ordered the crackdown on extremists holed up in the Lal Masjid in 2007. About 100 people, most of them extremists, were killed in the operation.
On the orders of the Islamabad High Court, a case was registered against Musharraf on September 2, charging him with the murder of Abdul Rashid and his mother.
The case was filed after the cleric's son submitted an application to police and referred to the Lal Masjid Commission's report, which held the former President responsible for the operation.
Musharraf has been held for nearly six months at his farmhouse, guarded by nearly 300 security personnel, including soldiers and snipers.
