Police in Baltimore -- including SWAT officers -- were trying Monday afternoon to disperse protesters who had thrown rocks and blocked traffic near a busy mall area. The protests follow the funeral of Freddie Gray, a black man who died while police in police custody in Baltimore.

Police tweets from the scene say "a group of juveniles in the area of the Mondawmin Mall" were blocking traffic, while there are reports of rock throwing. Armored SWAT vehicles were on the scene, but police were asking protesters "to remain peaceful."

Meanwhile, nearby University of Maryland-Baltimore has closed its campus, as have many area businesses.
