Madeleine Stowe: Naked & Afraid ... I Was Robbed at Gunpoint in My Home

Madeleine Stowe says she survived a terrifying ordeal -- a home intruder putting a gun to her neck in the middle of the night, and making off with $75k worth of jewelry.

According to law enforcement docs ... Stowe and her husband, Brian Benben, were asleep at home last September, when she was awakened by someone rummaging through their master bathroom. Madeleine, who was nude at the time, says she went to check it out -- and was confronted by a Latino man, the intruder, who pointed a handgun to her neck.

The former "Revenge" star told police the man spoke in broken English and demanded, "I want all the valuable, I want something." She says she gave him a bag filled with $75k worth of antique jewelry, and then he made a clean getaway.

A few months later cops busted the suspect, Walter Canizalez, as he was allegedly attempting another heist. Police believe he's pulled 3 other armed home robberies, and he's been charged with more than 15 counts ... including robbery and sexual battery.
