Just hours after Freddie Gray’s funeral, protesters clashed with police stationed near Mondawmin Mall in northwest Baltimore. At least seven officers have been injured, according to police, and there are reports of several arrests. One of the officers is reportedly unresponsive.

Early reports indicate many of the protestors are high school students who gathered at the mall as part of a demonstration organized on social media. Reporters for CBS Baltimore and the Baltimore Sun report that rocks and bricks were thrown at police, who responded with pepper spray. You can watch a livestream of the demonstrations here.

Many businesses and schools throughout the city have closed early, and there are reports of looting at a CVS. As the protests move south, police have set up barricades in front of City Hall and police headquarters.
