Richmond Police and Virginia State Police said they arrived at the monument around 10 p.m. to disperse a crowd of between 75 and 100 people because the monument’s park is closed after sunset.
Although some protesters left, others remained and one person or people shot paintballs, hitting four officers and one soldier, police said.
People also threw things at officers, police said. At some point, people fired fireworks at soldiers, according to the Virginia State Police.
At least one fireworks “went out of control” and hit one person in the median, state police said.
At 11:35 pm, the police had arrested five adults and a minor. All six were detained on initial charges of trespassing or trespassing.
The minor was also accused of assaulting a law enforcement officer, accused of shooting paintballs, police said.
