A Minnesota woman assaulted a flight crew member while aboard a jetliner from Las Vegas to Grand Forks, N.D., in January, according to a federal indictment.

Jody Lynn Sherry-Berg, 64, of Bemidji, was arrested Tuesday and charged in U.S. District Court in Fargo with interference with flight crew members and attendants during the Jan. 16 flight.

Sherry-Berg remains free on her own recognizance; a hearing was scheduled for April 21. Court records did not list an attorney for her.

The felony indictment did not reveal what prompted the alleged assault.

Sherry-Berg told the Minnesota Star Tribune that she was traveling home from an uncle's memorial service in Arizona when "I had a medical emergency and don't know what happened."

"I was hospitalized for two days," she said. "I'm horrified that this is happening."

Sherry-Berg said she believes the encounter occurred as the plane landed.

According to the indictment, she "did knowingly interfere with the performance of the duties of J.M., a flight crew member or flight attendant ... by assaulting and intimidating the flight attendant or flight crew member.

"Specifically, Jody Lynn Sherry-Berg assaulted J.M. by grabbing J.M.'s genitals."

The indictment did not specify whether the Allegiant Air employee was a pilot, co-pilot or flight attendant.

Sherry-Berg also was charged in Grand Forks County District Court with a misdemeanor for allegedly giving law enforcement a false name upon her arrest. That case was dismissed.
