1 injured after shootout inside Downtown Pittsburgh Arby's

PITTSBURGH (KDKA) -- A person was injured after a shootout inside an Arby's restaurant in Downtown Pittsburgh on Thursday.

Pittsburgh police said they were called to the Arby's on Liberty Avenue and Wood Street after 15 shots were fired between two people just after 3 p.m. 

When police got there, the two men were gone. Police said officers found and detained one of the men not far from the scene with a gunshot wound to his upper left leg. He was taken to the hospital in stable condition. His identity wasn't released. 

The second suspect, a man believed to be in his mid-twenties, is still on the run, police said. Investigators are reviewing all available video footage as they continue their search. 

Police said the initial investigation shows the two men possibly knew each other and had some sort of fight before shots were fired. 

"There were patrons and workers inside the restaurant so there's absolutely a danger to others," Pittsburgh Police Chief Larry Scirotto said. 

He said the manager hid in the freezer and called 911. While there were employees and patrons inside the Arby's at the time of the shooting, no one else was injured. 

"When there are individuals who are intent on causing harm to one another, our presence alone, all of our efforts to combat that just simply don't and won't," Scirotto said.

Officers recovered a gun from the area of Fifth Avenue and Wood Street.  

The crime scene unit processed evidence at the scene, and violent crime unit detectives will continue to investigate. 

A glass window near a side door of the Arby's was shot out. It was boarded up, and the store closed for the night. 

In October, a teenager was stabbed outside the restaurant, and in January a man was shot and killed on the sidewalk near Liberty and Wood. Another man was shot in Downtown Pittsburgh in June, and three people were shot on Smithfield Street in September. 

Pittsburgh police are launching a new unit next month to try and stop the violence. The unit will focus on gun violence, police said. 

"The access to firearms is an issue, the access to illegal firearms is still an issue," the police chief said. "When people have that level of intention, it's very difficult to disrupt that."

Scirotto told Pittsburgh City Council that violence is trending down compared to this time last year.
