Pakistani police have arrested former military ruler Pervez Musharraf over the killing of a senior Baloch leader in 2006.
Prosecutor Hassan Kakar said a three-member team of senior police officers from the southwestern province of Balochistan began questioning Musharraf on May 2.
The investigation is related to the killing of Nawab Akbar Bugti.
The Baloch leader died during a military operation ordered by Musharraf in August 2006.
Musharraf is already under house arrest until May 14 in separate cases related to his imposition of emergency rule, the dismissal of high-ranking judges in November 2007, and his alleged failure to protect former Prime Minister Benazir Bhutto, who was assassinated in December 2007.
Musharraf returned to Pakistan last month after four years of self-imposed exile but has been barred from running in upcoming parliamentary elections.
