He was produced in the court of the judicial magistrate.
The 69-year-old leader had fled from the Islamabad High Court after Justice Shaukat Aziz Siddiqui cancelled his bail and sought his immediate arrest. Musharraf had appeared in the court on Thursday morning to seek extension of his interim bail in the case related to the sacking of over 60 judges during the emergency of 2007. His bodyguards whisked him away before the police could act.
The Islamabad administration later declared his residence as a sub-jail. The police had earlier written to the authorities to make the move as there is threat to his life.
Musharraf's legal representatives are expected to move the Supreme Court later on Friday to appeal against an arrest order issued by the Islamabad High Court. The former Pakistan president had spoken to his aides and legal experts and decided to approach the apex court for a breather, sources in his All Pakistan Muslim League (APML) told the media.
APML secretary general Muhammad Amjad said since the Supreme Court had already announced that Musharraf would not be arrested for another case seeking his trial for treason, they would approach the latter to confirm his bail.
The former military dictator, who had toppled a civilian government through a coup in October 1999, returned to Pakistan from a five-year self-exile last month to contest the May 11 elections. But his nomination papers from all the constituencies he wanted to contest from were rejected.
