Arlington police used pepper spray Friday night to break up a large brawl at Washington-Lee High School’s homecoming football game against McLean High School. One adult was arrested during the game and charged with assault, but police did not release a name.

The fight involved at least 20 parents and students who were sitting in the stands. Arlington County Police spokesman Capt. Bruce Benson said the fight, which occurred about 8:30 p.m., was the result of a dispute between two families.

“It had nothing to do with the school, the game or the rivalry,” Benson said. “It was an unfortunate time for those groups to come together.”

There were no major injuries. Police are continuing to investigate the incident and may charge others, Benson said.

The schools are more renowned for their academics than their football teams. Washington-Lee won the game 55-19.
