Protests began in Baltimore Wednesday morning during the first court hearing for the six police officers charged in the death of Freddie Gray, an unarmed black man who suffered a fatal spinal cord injury while in police custody in April.
During the pre-trial hearing, prosecutors and defense lawyers argued on key motions in the case before the Judge Barry Williams, including a request to force Baltimore State's Attorney Marilyn Mosby to recuse herself from the case and motions on alleged prosecutorial misconduct.
The police arrested one protester, identified by witnesses as Kwame Rose, who was apparently injured after being hit by a car.
Outside the courthouse, one protester was using a megaphone to talk about getting justice for Gray and how the protests would take a break until 6:30 p.m.
But Rose — a hip hop artist and social activist — grabbed the megaphone and led the protesters on a several-block march toward the Inner Harbor.
Around there, witnesses told BuzzFeed News, he was hit by a car in the street. He was injured.
Police initially handcuffed him and placed him in a van. They later removed him and put him in an ambulance, where he is being treated.
This video of Rose's arrest shows protesters yelling at police to "let him go" and Rose is heard saying, "I got hit by a car."
Protesters chanted "take the cuffs off" for Rose while he awaited medical care.
Baltimore Police Commissioner Kevin Davis later alleged the protester assaulted the police officer, who suffered minor injuries.
In an interview with WBAL NewsRadio, Davis said "this young man kicked a police officer in the face and that's unacceptable."
However, some witnesses refuted the commissioner's account, saying they did not see Rose kick the officer.
Police later said that the protester was arrested for blocking a roadway and failing to leave after a warning.
Around 50 to 75 protesters had blocked the roads, according to Baltimore police who confirmed they had arrested one person.
There were at times tense confrontations between Baltimore police and protesters.
Police in riot gear asked protesters not to block the roads and move to the sidewalk.
Despite some tense moments, Davis and Mayor Stephanie Rawlings-Blake commended the police department's response to the protests in a press conference Wednesday.
"Today was a good day for Baltimore," Davis said. "Protesters exercised their First Amendment rights, police gave them space."
Rawlings-Blake said officials would prepare for any future protests according to the intelligence received by police.
"We're prepared and the lawlessness we saw in the past won't happen again," she said.
