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.

School officials say three students were shot outside a Pittsburgh high school, and police are searching for a gunman.
Pittsburgh school district spokeswoman Ebony Pugh says the students were shot outside Brashear High School on Wednesday afternoon as they walked to a vehicle they'd all taken to school earlier in the day.
She says their injuries appear to be non-life-threatening. Two were grazed in the head and one was shot in both the foot and arm. It's not clear who shot them.
Pugh says the victims were not on school property but close by. She says one victim was found inside the school but either ran inside or was taken there by emergency crews and wasn't shot inside school.
Brashear is about two miles south of downtown. Police have closed roads nearby.
