Islamabad's police chief Bani Amin said on April 23 that police found an explosive-laden vehicle parked some 150 meters from the main gate of Musharraf's house, located in the capital's outskirts.
The former military ruler has been held under house arrest since April 21 in connection with a case involving his decision to fire senior judges while in power. He will remain in judicial custody for two weeks.
Amin said police were investigating how the vehicle, which has been transferred to a local police station, was able to park so close to Musharraf's house.
The Taliban have threatened on numerous occasions to kill Musharraf, who returned to Pakistan last month after over four years in self-imposed exile.
