Officer Clashes With Protester After Freddie Gray Decision

Video shows the man fall to the ground among a group of protesters as more police rush in and drag away the man.

A sheriff's deputy struggled with a demonstrator during protests about the outcome of the first trial related to Freddie Gray's death. 

CBS News aired footage showing an officer in a green uniform pushing a man backward into a wall. The man falls to the ground among a group of protesters as more police rush in and drag him away. 

Baltimore braced for protests after a judge declared a mistrial in the case of Officer William Porter. He was the first of six cops to go on trial for the death of the 25-year-old Gray, who suffered a fatal spinal injury while in police custody. The jury deliberated for three days, but couldn't agree on a verdict on the charges of manslaughter, second-degree assault, misconduct in office and reckless endangerment. 

The brief footage showing the scuffle between the sheriff's deputy and protester leaves many questions unanswered about what came before and after the video was shot. CBS reported that the man had been carrying a bullhorn, but the reporter didn't see what sparked the altercation. 

Police made two arrests soon after the mistrial was declared. Baltimore Mayor Stephanie Rawlings-Blake and Gray's family called for calm. 

UPDATE: 11:24 p.m. -- Police arrested Kwame Rose, 21, a well-known local
activist, and a 16-year-old boy. The Baltimore Sun reported they faced charges that included failing to obey an order and disorderly conduct.
