TUCSON, Ariz. — Border Patrol agents from the Tucson Sector have arrested a convicted felon for illegally entering the country.

They say 43-year-old Esmeralda Mendez Madrigal is a registered sex offender and previously was deported following a six-year prison sentence for aggravated kidnapping and unlawful restraint.

Authorities say the Mexican woman was convicted on felony charges in Cook County, Illinois.

Border Patrol officials say Madrigal was arrested Wednesday near the Lukeville Port of Entry.

They say she now faces felony immigration charges. It was unclear Thursday if she has a lawyer yet.
