Vic Mensa clashed with police during a protest in Chicago last night.

Protestors took to the streets after Chicago police released a graphic video showing officer Jason Van Dyke shooting black teenager Laquan McDonald 16 times. The officer was this week charged with first-degree murder over the killing, which took place in October last year.

Local rapper and Kanye West collaborator Vic Mensa joined the protestors and was later caught on video in a clash with police, as Pitchfork reports. Footage captured by CBS News appears to show the clash.
