Terence Crawford was held by a police officer at gunpoint and cited for reckless driving early Sunday – shortly after a parade in his honor – in his hometown of Omaha, Nebraska.

Police say the officer pulled out his gun after he saw a firearm on the driver’s side floorboard, after which the four occupants were ordered to exit the car.

Crawford reportedly was released at the scene.

An Omaha Police Department statement, approved by both Mayor John Ewing and Police Chief Todd Schmaderer, indicated that Schmaderer has authorized an internal affairs investigation into the incident.

The statement reads in part:

"Shortly before 1:30 a.m., officers working in the downtown area observed a vehicle driving recklessly near North 12th and Capitol Avenue. A traffic stop was conducted at Cass Street.

“While speaking with the driver, an officer observed a firearm on the driver’s side floorboard. For safety, all four occupants were ordered out of the vehicle at gunpoint. The driver was later identified as Mr. Crawford upon verification of his driver’s license and was issued a citation for reckless driving. One passenger, a member of Mr. Crawford’s security team, was also found to be carrying a legal firearm.

“Police have confirmed that all occupants are legally permitted to carry firearms. A police supervisor and lieutenant responded to the scene at Mr. Crawford’s request.”

Ewing released a separate statement. He said: “I learned Omaha police pulled over Terence ‘Bud’ Crawford on a traffic stop downtown early this morning. After learning of this, I spoke personally to Bud Crawford. I acknowledge the seriousness of what occurred and how trust between law enforcement and our community is important and shows the need to be continuously vigilant about building relationships. Omaha Police Chief Todd Schmaderer has pledged an internal investigation, which I support and want to be full and thorough. We will gather all the facts and be transparent with the public about our findings.

“Understand that my heart dropped in learning of this end to an otherwise wonderful day and evening celebrating our city’s world boxing champion. We held a great parade and great event at Heartland of America park. The evening birthday party at Steelhouse, which I and members of my team attended, was a showing of joy and pride. Omaha needs to remember this important day as a good one while we seek answers to how it ended. Meanwhile, we must ensure that every resident, no matter who they are, feels safe and respected in Omaha.”

In a video of the incident, apparently taken by one of the passengers and widely circulated, the officer can be heard saying, “Unbuckle the seat belt and step out.” Crawford complies by removing his belt and then saying nervously, “I’m opening the door, I’m opening the door.” Crawford then said in response to something the officer said, “I’m not reaching for no gun.”

Crawford stepped out of the car with his hands up, was patted down and reportedly handcuffed. He can be heard talking with the officer when the video ends.

Qasim Shabazz, head of Crawford’s security, spoke to Omaha news station First Alert 6 after the incident.

“Man, I thought we were getting ready to lose our lives," he said. "... That was a nightmare, you know, future husband, just had a brand new child and children and stuff like that.

“To know that I almost lost my life last night because we had a police officer that does not know how to articulate a traffic stop.“

A parade in the boxing star’s honor was held Saturday celebrating his career-defining victory over undisputed super middleweight champion Canelo Alvarez on Sept. 13.
