PITTSBURGH — Police have a teen in custody, but haven’t said whether he’ll be charged in a shooting that left four wounded after the city’s Fourth of July fireworks display.

Police have said they’re looking for two young black men, one dressed in black and the other wearing a white dress shirt over another white shirt.

Police said they were arguing when shots were fired about 10:30 p.m., as people were leaving the display. A woman was shot in the head and was in critical condition and a man was shot in the leg. Police said a boy and girl were each also shot in the leg.
