Federal agents and sheriff's deputies stormed the cockpit of a Delta Airlines flight from Minneapolis to San Francisco over the weekend and arrested the co-pilot on child sexual assault charges, authorities said.

The Contra Costa District Attorney's Office has now charged 45-year-old Jennifer Powell in the case. Powell is the mother of the girl who survived the abuse.

A Delta pilot arrested after landing at a San Francisco airport has been charged with several felonies related to the sexual abuse of a child, officials say.
