There's been another school shooting, this time in Philadelphia.  We're seeing reports that at least two kids have been shot.  One suspect is in custody but police are searching for at least one other person.

The police dispatch call said "two kids, a male and a female, both shot in the arm" as calls came in to 911 after the shooting.

More info from NBC10 in Philadelphia:

Two 15-year-old students -- a boy and a girl -- were injured in the shooting, which took place near the gymnasium, police said. The boy was hit in the arm and the girl appears to have been grazed by the same bullet, police tell NBC10.

Philadelphia Police Commissioner Charles Ramsey says there were seven students inside the gym when the shooting happened and that the entire incident was caught on surveillance video.

Parents told NBC10 reporters on the scene that there have been several fights at the school recently and that they had concerns about safety.

Police say the school does have security. The building is also equipped with metal detectors, so investigators are trying to figure out how the student was able to get the gun into the school.
