SWISSVALE, Pennsylvania (WPXI) -- Swissvale, Pennsylvania police are investigating two fights at a Woodland Hills School District bus stop involving 60 to 70 people on Monday and Tuesday.
According to police, the first fight happened at a bus stop near the intersection of South Braddock and Woodstock avenues on Monday. Then a second bigger fight broke out at the same location Tuesday.
Investigators are calling the fight a riot because of the large number of people involved. Police said they're using video of the fight to help identify those involved.
"Everyone will be arrested. Anyone with any involvement at all will be arrested," Swissvale Police Chief Greg Geppert said.
Geppert said it is not clear what the fight was about and some detectives called it the biggest brawl they've ever seen in this neighborhood.
