Denver blocks police from using chemical agents against protesters

U.S. District Court Judge in Colorado banned the Denver Police Department from using tear gas, pepper balls or projectiles of any kind against peaceful protesters, local media reported. 

The ruling came a day after four Denver residents filed a lawsuit against the city claiming the city's police violated the protesters' constitutional rights during a recent protest. 

U.S. District Court Judge R. Brook said in the ruling that actions of some law enforcement officers in Denver and across the nation "disgusting", adding that "the Denver Police Department has failed in its duty to police its own".
