WASHINGTON, June 22 (Xinhua) -- Hundreds of protesters took to the streets in East Pittsburgh, a borough about 10 miles east of Pittsburgh, for the second straight night till early Friday morning over the fatal police shooting of a 17-year-old African American boy.

At least one female protester was taken into custody, according to a report by CBS Pittsburgh on Friday.

Protesters demonstrated outside the East Pittsburgh police headquarters on Thursday night, then began marching through the streets, eventually shutting down a busy highway for about two hours by 11 p.m., backing up traffic for miles, said the report.

Around 1 a.m. Friday, police told demonstrators still on the scene to leave or be arrested. Around 1:30 a.m., police began arriving in riot gear to try to break up the lengthy protest. Just after 2 a.m., police began moving in on the few protesters left, said the report.

Antwon Rose Jr. was shot dead by a police officer on Tuesday when he was fleeing from a traffic stop in a confrontation partly captured on video and posted on Facebook by a bystander.

Police had stopped the car he was riding as part of an investigation into an earlier shooting. The video shows the officer firing three shots seconds after Antwon and another passenger are seen running from the car. A lawyer for Antwon's family said the boy didn't pose an immediate threat to anyone.

Allegheny County police are conducting an independent investigation of the shooting. The officer who shot the boy dead has been placed on administrative leave.
