A passenger on a Frontier Airlines flight from Denver to Houston broke a window while the plane was in the air this week. Other fliers had to restrain him for the duration.

The restrained man began his outburst 20 minutes into Wednesday’s Frontier Flight 4856 out of Denver International Airport.

Police told Houston’s KRIV that the man tried to speak to a woman in the row in front of him, then punched and kicked the seat and nearest window when she didn’t respond. 

She then asked for a seat change, and “he immediately stood up and started punching the window and kicking at it. … He proceeded to punch the window until one of the men grabbed his arm and twisted it behind him. He was able to shatter the first layer of the window before being stopped,” passenger Victoria Clark told social media agency Storyful.

Other passengers told the TV station that the man was screaming in Spanish.

Several male passengers stepped in to restrain him, using zip ties and shoelaces to bind him, as captured on video posted on YouTube by Storyful Thursday.

“He was very physical. I picked him up and put him on the ground. It took a couple of guys to get his arms behind him and secured,” Tanner Phillips, another passenger and a military veteran, told Houston’s KTRK-TV.

The plane landed at George Bush Intercontinental Airport at 11:10 p.m., according to FlightAware.

Frontier Airlines declined to press charges upon landing, and as such the Houston Police Department hasn’t identified the disruptive passenger. The FBI, however, is investigating the incident, according to KHOU.
