TSA: Woman Tried to Bring Stun Gun on Plane in NYC Authorities say a college student from China was arrested trying to carry a combination stun gun and flashlight onto a plane in New York City. Sihui "Hannah" Xie said by phone Sunday that she pleaded not guilty and believes her weapons-possession case is on track to be resolved with a fine. Court records aren't immediately available. The Transportation Security Administration says a checkpoint screener spotted the item in Xie's carry-on luggage as she headed for an Orlando, Fla.-bound flight at Kennedy Airport. The TSA says the device initially just appeared to be a flashlight, but the screener looked more closely and saw it also was a stun gun. Xie was then arrested. She's a student at Fort Hays State University in Hays, Kan.
