Four people were arrested after a large disorder at a basketball game in Washington County Friday night.
An unruly crowd of about 40 or 50 people gathered in the parking lot after the game between Washington County High School and Marion County High School, state police said.
Two adults, Pamela D. Railey, 44, and Chelsea Railey, 18, both of Springfield, as well as two juveniles who were not named, were arrested and charged with disorderly conduct and resisting arrest.
One of the juveniles was also charged with assaulting a police officer and criminal mischief.
Two state police officers, Fred Cornett and John Adams, were working at the game and received scratches and abrasions during the incident.
The Washington County High School principal had requested additional police presence before the game because he anticipated problems.
"It's a very heated rivalry between neighboring counties," said state police Trooper Billy Gregory.
