CHICAGO -- Three protesters were detained Tuesday night during demonstrations in Chicago over the killing of a black teenager by a white Chicago police officer.
Protesters were blocking traffic Tuesday night on the city's near West Side. Some circled police cars in an intersection and chanted "16 shots."
Protesters took to the streets after Chicago police released the video of 17-year-old Laquan McDonald's 2014 death. Prosecutors Tuesday charged Officer Jason Van Dyke with first-degree murder.
Chicago Police Superintendent Garry McCarthy says the department is prepared to handle protests and urged they be peaceful.
Protesters say they are headed to 17th and State to show solidarity with the three people detained.
