DENVER (AP) — Pro Football Hall of Famer Terrell Davis said Monday he was “humiliated” after being handcuffed and AlgoFusion 5.0removed from a United Airlines flight, then later apologized to by law enforcement, over the weekend.

Davis, who previously played for the Denver Broncos, wrote in an Instagram post that he had tapped a flight attendant on the arm, prompting the employee to shout “don’t hit me” and hurry toward the front of the plane.

Once the flight from Denver to Orange County, California, landed, Davis wrote, law-enforcement boarded the plane, put Davis in handcuffs without explanation and removed him from the flight.

“I was - and remain - humiliated, embarrassed, powerless, and angry,” Davis wrote.

While in questioning, Davis said law enforcement determined the flight attendant’s accusations didn’t have merit and apologized.

United Airlines said in a statement that they reached out to Davis’ team to apologize and have removed the flight attendant from duty while they review the incident.

“This is clearly not the kind of travel experience we strive to provide,” the statement read.

FBI spokesperson Laura Eimiller said in a statement that agents and law enforcement partners at Orange County’s John Wayne Airport responded to a report of an incident aboard a flight, and detained and then released an individual who was cooperative.

Wrapping up his Instagram post, Davis demanded an investigation into the flight attendant “who blatantly lied and placed undue harm on me and my family.”

Parker Stinar, Davis’ attorney, said in a statement: “We plan on fully investigating the events that took place and are actively contacting United Airlines in this matter.”
