PITTSBURGH (AP) --Pittsburgh police say they've taken four people into custody for questioning about a shooting that wounded three students outside a city high school.
Spokeswoman Diane Richard says police believe the shooting outside Brashear High School after classes ended Wednesday might stem from a drug-related dispute between students at the school last month.
She says those in custody are not suspects or necessarily going to be charged. Police aren't saying whether they're also students.
Police say the victims were not immediately cooperating with investigators.
The victims are all boys. Two are 17 and one is 16 years old. None were seriously wounded.
