Hall of Fame running back Terrell Davis posted on Instagram that he was handcuffed and questioned by FBI agents Saturday after a United Airlines flight attendant accused Davis of hitting him. The Denver Broncos Ring of Famer said he is demanding a thorough and proper investigation. He said the experience was "traumatizing" and that it left him "humiliated, embarrassed, powerless, and angry." "I am still in shock over the traumatizing events," he said. United Airlines issued an apology and took the flight attendant off the schedule. No charges were filed, and in a statement, the FBI described Davis as “cooperative” and said he was “released to continue his travels.” Davis – the Broncos’ all-time leading rusher and Super Bowl XXXII most valuable player – took to social media Monday to defend himself, saying Saturday’s incident unfolded after he touched the flight attendant’s arm to get his attention. Davis was flying with his wife and three children from Denver to Orange County, California, and simply wanted to ask the flight attendant for some ice for his son. Davis said that when he "lightly tapped" the flight attendant's arm to ask for the cup of ice, the flight attendant "shouted 'don't hit me,'" left their cart and went to the front of the aircraft. Davis said he was confused by the exchange and that he did not interact with the attendant for the rest of the flight.
