Jamil Akbar Bugti, the son of Akbar Bugti, had named Musharraf, former Prime Minister Shaukat Aziz and other high-ups in the murder of his father.
The Balochistan High Court has already issued arrest warrants for the accused persons.
Bugti was killed in a cave on August 26, 2006, during a military crackdown ordered by Musharraf who was the president and army chief at the time.
Bugti had led an armed campaign to press for provincial autonomy and a greater share of profits in Balochistan's natural resources.
The death of the Baloch chieftain sparked angry protests in the country.
