Nearly 200 people have been arrested in Houston, Texas, after protests Friday night.
Most will be charged with obstructing a roadway, according to a tweet from the Houston Police Department.
The department also said four of its officers sustained minor injuries and eight police vehicles were damaged.
Houston Police Officer's Union President Joe Gamaldi earlier said officers had been hospitalized but did not say how many.
"Our officers who were attacked are in the hospital, patrol cars ruined, businesses damaged," Gamaldi said in a tweet.
"This is not who we are as a City and as a community. We will protect your right to protest, but we will not allow our city to decay into chaos."
