The Contra Costa District Attorney's Office charged Rustom Bhagwagar and Jennifer Powell each with more than a dozen felonies, including counts of engaging in a sexual act with a child 10 years old or younger, oral copulation with a child, forcible lewd acts upon a child, and aggravated sexual assault of a child.

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.
