A 17-year-old boy has been arrested by Antioch police after a Domino’s delivery woman said she was kidnapped and raped at gunpoint Sunday morning while on her route.

“We are shocked and horrified by what happened,” Domino’s vice president of communications Tim McIntyre said in an email early Monday morning. “We couldn’t conceive of something like this happening, especially on a Sunday morning.”

According to Antioch Police Sgt. Dimitri Barakos, the woman was making a delivery on the 2800 block of Blue Bell Circle at 11:20 a.m. when she was robbed at gunpoint. She was then forced back into her vehicle by the teen who made her drive to an undisclosed location where he proceeded to sexually assault her.

Afterward, the delivery woman called police and the teen arrested in the area where the original robbery happened.

He was booked into juvenile Hall in Martinez. No more information was immediately released, but more details were expected to be released later on Monday.
