A Newark woman is behind bars, charged with threatening her ex-boyfriend and his female acquaintance with a knife.

Jessica Sachs opened her car door into her ex's back as he and the other woman were getting into their car outside the Cinemark Christiana Theater Friday night, Delaware State Police said.

Sachs allegedly threatened the couple with a large knife, but her ex was able to wrestle the knife from her and get her to leave.

Troopers picked Sachs up at her home and charged her with possession of a deadly weapon during a felony and aggravated menacing.

She was booked into the Baylor Women's Prison.
