A security guard was arrested after rushing to the stadium during an NBA final, in a recent incident involving fan misconduct at a sports event.
The man ran into court disrupting Monday's final match between the Washington Wizards and Philadelphia 76ers in Washington, D.C.
Monumental Sports & Entertainment, which owns Capital One Arena and the Wizards, wrote on Twitter that the man had been suspended.
"Monumental Sports & Entertainment has a policy of intolerance if fans violate our Code of Conduct at Capital One Arena," the company said.
He said the cases were being investigated by the Metro Police Department, but police did not immediately respond to a request for comment on Monday night.
Like many teams, Washington started the season without fans on the stations, but the team has been increasing the power of the stadiums as the Covid-19 restrictions are lifted. In Monday night's game, the crowd was 10,665, about 50 percent of the area's population, reports the Associated Press.
The 76ers fell to the Wizards, 122-114, in Game Four of their series in the first round of the NBA playoffs.
There have been other recent incidents involving fans in NBA games that have ended in arrests or closures.

A Boston Celtics fan was arrested on Sunday and accused of throwing a water bottle at Brooklyn Nets guard Kyrie Irving after the Nets beat Celtics at TD Garden in Boston.
On Wednesday, a 76ers fan threw Wizard Russell Westbrook at popcorn. The fan was stripped of his season ticket and banned from all events at the Wells Fargo Center. The 76ers apologized to Wizards and Westbrook.
The New York Knicks on Thursday said it was blocking a man who spat at the Atlanta Hawks guarding Trae Young. The team also apologized for the behavior of the fans, calling it totally unacceptable.
Last year, fans were banned from the games after the NBA was shut down and resumed playing in the "bubble" competition due to the Covid-19 epidemic.
The league said last week that as more fans were allowed to return to watch the games in person, a stronger morale would be developed.
After the game, Wizards coach Scott Brooks called Monday's incident a "disgrace" and said fans who behaved in a recent manner should be punished. "It's just been happening, and they're not scared at all," he said.
"I don't know the law. I just know you shouldn't have been able to do that and then run away and just be fired," Brooks said.
