Doug Adams, 26, was removed from the Virgin Airlines flight he was on Monday morning after the plane made an emergency landing because of a patient having a "medical emergency."
Witnesses said that Adams had a hospital bracelet on his wrist and appeared to be on drugs.
Los Angeles-based filmmakers Sam Slater and Paul Bernon, who were sitting in the row in front of Adams told CBS Los Angeles said the suspect kept mumbling about not trying to be violent, and how he didn't want to be a violent person.
"We’re sitting in the front row, and we’re both a little concerned and watching what’s happening,” Slater told the station.
Bernon said the situation seemed to escalate after Adams returned from the restroom.
“When he came out of the bathroom, he sat back down, he was arguing with the woman next to him, said he didn’t want to sit next to her,” Bernon told CBS Los Angeles. “He got back up, told the attendant he wanted her to move, and at that point they paged to see if there was a doctor on board.”
A doctor took Adams' blood pressure and the flight crew cleared a row in the back of the plane and isolated him from other passengers.
“He at that point was fidgeting and began to remove the plastic covering from the emergency exit door, and tried to pull to open the door,” Slater said. “Fortunately, there were a couple of Boston police officers on the flight that were there to help as well. And that’s where we realized that we weren’t going to make it to Los Angeles and we had to land in Omaha.”
When the plane landed in Omaha, he was led away in handcuffs, MyFox8.com reports.
He was taken to a hospital for observation, ABC7 News reports. The rest of the passengers arrived in Los Angeles shortly after noon.
The Omaha Police Dept. has not responded to HuffPost inquiries about whether Adams has been charged.
