By Thursday and Friday, protests in the name of Baltimore prisoner Freddie Gray had spread to a number of other cities across the country. In some cases, the violence also followed along with the protests and arrests were made.

Nearby New York was one of the first to see Freddie Gray protests spread among residents, and in the Big Apple, at least 100 were arrested.

Protesters gathered in Union Square in New York on Thursday afternoon. Authorities reported that the demonstration grew to up to 1,000 participants.

Protests had occurred on Wednesday, as well, with over 120 protesters arrested.

Several hundred Protesters also gathered in Philadelphia for a march organizers called “Philly is Baltimore.”

The Philly demonstration in Dilworth Plaza was initially peaceful as chants of “no justice, no peace” rang out. But it wasn’t long before police became targets of rocks and bottles. Some arrests were made.

Protests in Chicago, though, stayed peaceful as several hundred demonstrators marched outside Chicago Police Headquarters.

Speakers in Chicago spoke out against police brutality in Chicago, one warning the audience not to run from police because “they’re going to kill your a**.”

Demonstrations also occurred in Washington D.C., Boston, Minneapolis, Indianapolis, Houston, and other major cities
