PHILADELPHIA (AP) -- Philadelphia police say a boy charged with aggravated assault was expected to surrender Saturday in connection with a shooting that wounded two students inside a high school gymnasium.
Police say another boy already in custody in Friday's shooting at the Delaware Valley Charter High School in north Philadelphia has not been charged yet.
Police aren't identifying either boy because of their age. They say they've been in contact with the second suspect's parents and expected him to turn himself in.
Police said two students were wounded in what may have been an accidental shooting.
Authorities say a girl was treated and released after the bullet struck her a bicep. The same bullet then hit a 17-year-old male student who remained hospitalized in stable condition.
