A vigil held in honor of Elijah McClain on Saturday in an Aurora, Colorado park turned violent when police officers wearing full riot gear were seen charging toward a group of participants.

The vigil, which was part of a larger rally, was organized by Denver's Party for Socialism and Liberation and included a performance by violinists as an ode to the 23-year-old, who was known for playing his instrument to shelter animals, according to The Cut.

Mic reported there were thousands of people at the demonstration, including families with small children.

Six-time Grammy nominee Ashanti Floyd and Lee England Jr. were two of the musicians who performed on Saturday. 

As people listened to the violinists while holding signs calling for justice, officers marched into the park and deployed a chemical agent.
