NORTH SIDE (KDKA) – Pittsburgh Perry High School was placed on lockdown Thursday morning due to a shooting outside.

According to police, a 17-year-old male was shot outside of a convenience store near the intersection of Baytree Street and Perrysville Avenue just before 9 a.m. The teen ran into the school and was treated by the nurse until paramedics arrived. He was taken to Allegheny General Hospital in serious condition with a gunshot wound to the hip area. He has since been released.

The school was quickly placed on lockdown, which was lifted about an hour later.

“I wasn’t terribly scared, because it’s a pretty good school security-wise, but it’s just too close to home,” said parent Malik Hayes.

“We’re trying to figure out what led up to the shooting,” Pittsburgh Police Spokeswoman Emily Schaffer said.

Three male juveniles fled the scene, but were detained for questioning within 15 minutes.

After the three were taken to headquarters, police and their K-9 officers searched the woods off of Waldorf Street for the weapon. They found one near a set of steps. Right now, it is believed to the gun used in the shooting.

One shell casing was also found outside of the school.

About an hour later, a fourth juvenile was led out of Perry High School and put in the back of a police car. He was taken to headquarters for questioning as well.

One minute before the shooting, surveillance video from inside the convenience store shows a group of young men walking in and then leaving. It is not clear right now if they are connected to the shooting.

Police haven’t said if these are the teens involved in the shooting, but police did review the footage as part of the investigation.

“We are reviewing surveillance to see about additional information,” Schaffer said.

So far, no one has been charged in the case.

Meanwhile, parents were alerted to the incident through the district’s notification system.

As a safety measure, the school district has changed the time for Friday’s football game between Perry and Westinghouse from an evening game to an afternoon game. No fans will be allowed in the stadium.
