The number of protesters on the streets of Baltimore grew quickly Wednesday as hearings began in the Freddie Gray police brutality case.

A handful of people were out early with signs near the courthouse. At times, the group shouted, “Black Lives Matter.” One protester who spoke said, “I could have been Freddie Gray on that day.”

Baltimore police tweeted that they had arrested one person. “No taser deployment,” the Twitter message read.

The protesters came out Wednesday as the first circuit court hearing began for six Baltimore city police officers charged in the arrest and death of Gray.

Gray’s arrest and death in April sparked riots that prompted leaders to call in the National Guard.

Gray died from a severe spinal injury he suffered while in a police transport van. His case set off a national debate about the death of young African-American men in police custody.
