Sarah Maria Beach, 45, an American expat living in London, faces misdemeanor assault charges which were filed in US district court in Utah on Thursday.
News of Beach’s arrest was reported by KSL.com.
Prosecutors have alleged that Beach threw coffee on passengers during the flight, overturned a drink cart, and ran up and down the aisle of the plane.
Flight attendants asked air marshals who were sitting in the back of the plane to help subdue Beach, according to the criminal complaint.
After Beach calmed down, she was seated next to one of the air marshals, who escorted her to the bathroom three times.
After she came out the third time, she allegedly jumped on the air marshal’s back and grabbed his head, neck, and jaw.
