The Morgantown police department and nearby responding agencies arrested 15 people in the "destructive aftermath" of the West Virginia University-Texas football game Saturday night.
About 1,000 people took to the streets, requiring police presence from several agencies, including Morgantown police, university police and West Virginia state police.
Police extinguished about 30 fires and charged five people with arson-related offenses. The other ten charges ranged from battery on an officer to disorderly conduct, according to a statement from the Morgantown police department.
Several officers received minor injuries controlling the crowd, police said, but none required medical treatment.
Roughly 50 officers carried batons and were wearing protective helmets, gas masks and body armor and to protect themselves from rocks, bottles and other objects the crowd threw at them, police said.
Officers used pepper spray and gas against the group, some of whom were fighting and attempting to overturn vehicles.
Officers will meet this week to discuss how to respond to future problems, police said.
The Mountaineers are undefeated so far this season.
