Baltimore Police opened fire on demonstrators Monday following the funeral of Freddie Gray, who died earlier this month in police custody from injuries sustained during his arrest. It wasn’t clear what ammunition was fired, but there were Twitter reports that rubber bullets were used. To watch live stream footage of the events, click here. Many of the protesters seemed to be teenagers, the Huffington Post reported.

At least seven officers were injured, according to the Associated Press, and at least two police officers were unaccounted for, Baltimore Sun reporter Yvonne Wenger tweeted.

The Baltimore Police Department was active on Twitter during the protest and posted updates every few minutes.

“Despite having rocks, bricks, and other items thrown at us -- officers are using fire extinguishers to put out small fires in the area,” the BPD tweeted Monday. “A large group has surrounded a police car at North Avenue and Pennsylvania Avenue. The group is destroying the police car.”

The crowd of people had become “violent and aggressive,” and the BPD asked that marching protesters stay away from Pennsylvania Avenue and move toward Baker Street.

As looting began in the area, the BPD Twitter feed said that other resources were deployed “to ensure everyone remains safe,” but the BDP did not identify those resources.

A Special Weapons and Tactics (SWAT) team arrived on the scene, according to Twitter user Agitator In Chief.
