About 500 people marched on the West Side of Chicago Wednesday evening to protest a police-involved shooting that claimed the life of an 18-year-old man on Sunday.

Roshad McIntosh, 18, was pronounced dead at Mount Sinai Hospital after being shot by police at about 6:30 p.m. on the 2800 block of West Polk Street in the Lawndale neighborhood, officials said.

A crowd of people marched to the Harrison District headquarters, 3151 W. Harrison St. and then ended their journey through the neighborhood in a vacant lot right next to the two-story apartment building where McIntosh was shot.

Police said he was armed.
