Musharraf's lawyer Ilyas Siddiqui filed the petition on his behalf. "We have filed a bail petition. The matter will be heard on October 18," Siddiqui told PTI.
Police in Islamabad arrested Musharraf on Thursday over the killing of cleric Abdul Rashid and his mother during the military operation against extremists holed up in the Lal Masjid.
Yesterday, a magistrate's court here remanded 70-year-old Musharraf to judicial custody for 14 days in the Lal Lasjid case while another court rejected a request to bar him from travelling out of Pakistan.
Musharraf was earlier granted bail in three other cases registered against him for the assassination of former premier Benazir Bhutto, the murder of Baloch leader Akbar Bugti and the imposition of emergency in 2007.

This had given rise to speculation about his possible release after nearly six months of house arrest but he was subsequently arrested for the killing of the Lal Masjid cleric.
Musharraf, who was then army chief and President, had ordered the crackdown on the Lal Masjid in 2007. About 100 people, most of them extremists, were killed in the operation.
Musharraf has been held for nearly six months at his farmhouse, guarded by nearly 300 security personnel, including soldiers and snipers.
He took power in a 1999 coup and ruled as President until he resigned when he was threatened with impeachment in 2008. He then went into self-imposed exile and returned to Pakistan in March in a bid to resurrect his political career.
