COVINA — An El Monte woman is behind bars on suspicion of kidnapping another woman and holding her at gunpoint for more than five hours while trying to make her sign over her car, authorities said Friday.

Lori Madrid, a 36-year-old gang member, was being held in lieu of $100,000 bail, according to sheriff’s officials and booking records.

A man called 9-1-1 about 3 a.m. Tuesday and reported his girlfriend, a 22-year-old Temple City woman, was being held hostage at gunpoint by Madrid at a home in the 16600 block of Tudor Street in an unincorporated county area near Covina, Los Angeles County sheriff’s officials said in a written statement.

Deputies from the sheriff’s San Dimas Station responded to the home where they freed the kidnapping victim, arrested Madrid and found a handgun, sheriff’s officials said.

The victim told deputies she went to the home to see a resident and was confronted by Madrid, her former neighbor, who was armed with a handgun, according to the sheriff’s statement.

While holding her for more than five hours, authorities said, Madrid threatened the victim in an attempt to get her to sign over the pink slip to her car.

Madrid was booked on suspicion of kidnapping, attempted robbery, possession of a loaded firearm, being a gang member in possession of a firearm, possession of an unregistered handgun and a gang enhancement charge.
