Here is an affidavit by Peter Carriacto, an FBI agent in Charlotte, about events on April 29 aboard US Airways Flight 705 from Frankfurt, Germany, to Charlotte. The agent says that passenger Raun Michael Brissenden interfered with the duties of the flight crew.
When flight attendants tried to restrain Brissenden, the affidavit says, he began poking other passengers and grabbed one passenger by the breast. He was restrained by two off-duty police officers and other passengers and detained in the back of the plane. He was arrested on arrival in Charlotte.
