PITTSBURGH (KDKA) – Demonstrators continued to call for equality as they march through Pittsburgh.

Pittsburgh Public Safety sent out an alert as several hundred moved into downtown.

They started out in Freedom Corner, where several speakers addressed the crowd.

Before that, a small group of Black Lives Matter protesters marched through the streets of downtown Pittsburgh.

They started the protest by sitting at the intersection of Liberty Avenue and Commonwealth Place, blocking the ramp to the Fort Pitt Bridge.

Demonstrators then moved through downtown, shouting phrases like “black lives, they matter here” and “three shots in the back, how do you justify that?”

As the group moved through the city, they sang out Freedom Fighters songs.

An email about the protest calls the protest “Pittsburgh Action For Black Trans Lives” rally and march.

They marched toward the City-County Building and sat on the steps. Speakers addressed the crowd of hundreds.

People in the trans community spoke to the crowd about how they have been marginalized and treated unfairly. They received support from the group.

They also chanted several times for the warden of the Allegheny County Jail to resign.

They remained peaceful.

Police blocked intersections both in front of and behind the crowd to ensure safe travel.
