Pakistani police say the country's former President Pervez Musharraf faces arrest if he returns to Pakistan.
Police registered a case Tuesday against Mr. Musharraf over his detention of judges during a political crisis in 2007. He could serve three years in jail if convicted.
Last month, the Supreme Court ruled that Mr. Musharraf violated the constitution when he imposed emergency rule and dismissed top judges in an effort to hold onto the presidency.
The former military chief resigned as president last year to avoid impeachment. He has been living in London the past two months.
Mr. Musharraf was replaced by Asif Ali Zardari, the widower of slain former Prime Minister Benazir Bhutto, whose Pakistan People's Party had won parliamentary elections.
