Protesters Rally for Freddie Gray Near Baltimore City Hall

About 200 people gathered near Baltimore City Hall Thursday to rally for Freddie Gray, a black man who died while in police custody.

Demonstrators yelled "no justice, no peace" and held signs that said "Freddie Gray." The 25-year-old Gray died of a mysterious spinal injury he suffered while in police custody.

Peaceful protests have been held for Gray for the past six straight days. Officials warned commuters of traffic congestion.

Gov. Larry Hogan's office said Thursday that a team of 32 troopers were being sent to help with crowd control at the request of Mayor Stephanie Rawlings-Blake. Baltimore police said it's common to ask for troopers to help with events that have large crowds.

Protesters splintered into two groups Wednesday night. One group cursed at police and threw some soda cans at them, while another group marched 20 blocks to City Hall, at times blocking intersections and disruption traffic as they shouted: "No justice, no peace."

Three people were detained, no one was hurt and the protests remained largely peaceful.
