A shooting broke out Saturday afternoon at the Springfield Mall parking lot following an argument inside the busy shopping center.
Springfield Township police said the argument happened between two groups of men who they believe shot at each other.
No one was injured during the chaos, which started just after 1 p.m., police said. The mall, located on Baltimore Pike in Springfield, Delaware County, was evacuated, according to police. All stores except for some anchor stores remained closed Saturday.
It is expected to open Sunday at its usual time, 11 a.m.
Several suspects fled the scene, according to officials. Four vehicles were damaged.
Officers armed with long guns could be seen clearing the mall as stores closed their doors and shoppers left the building.
The mall is a popular destination in Delaware County and is typically packed with shoppers during the weekends. Several people on Facebook commented about their experience Saturday afternoon.
"I was there. Never have been so scared in my whole life. Many thanks to the entire Delaware County police force for keeping us safe," Marissa Colmaire wrote on Facebook.
This is not the first shooting at the suburban mall. In 1985, Sylvia Seegrist opened fire, killing two men and a 2-year-old child. Seven others were also injured during the rampage.
