A “belligerent” passenger allegedly struck an airline employee with an intercom phone when they were asked to get off a Frontier Airlines flight leaving Denver International Airport.

The passenger – identified by Denver police as Shuri Turner – was asked to deplane a Tampa-bound flight after she “became belligerent onboard,” according to a statement from Frontier Airlines.

But Turner allegedly took matters into her own hands, CNN reported.

“As she was deplaning, she picked up an intercom phone and struck a flight attendant,” the statement said.

Denver police arrested Turner and charged her with assault, according to Denver7, a local ABC affiliate.

It’s not clear what spurred the confrontation. But the flight left Denver about four hours late because of the outburst.

Turner, meanwhile, was reportedly cited and released.

The Federal Aviation Authority has gotten about 670 reports of quarrelsome passengers this year, according to federal data.
