LIMA, Peru (AP) _ President Alberto Fujimori's deposed security chief, Vladimiro Montesinos, has been detained by the military, Peru's independent CPN radio reported Monday.

The radio station, citing an unnamed military source, said the order for the arrest was issued by Montesinos' close associate, Gen. Jose Villa Riestra, commander of Peru's armed forces.

The radio station said Montesinos' sister had already filed a request asking a court to order the military to free the 54-year-old security chief.

Montesinos, who was widely believed to control the judicial system, the attorney general's office and the military, was suspended from his position on Saturday when Fujimori announced he was ``deactivating'' the intelligence agency.

But unconfirmed reports said he had continued to operate as head of the feared spy network from his headquarters in a navy base in the capital, Lima.
