Two men were arrested. According to 9 News:
The damage happened during a planned protest that drew around 100 demonstrators, who marched from the Denver jail to police headquarters, a DPD spokesperson said. Some held signs in support of Jessica Hernandez, a17-year-old who was shot and killed by Denver Police last monthwhile she was driving a stolen car that ended up striking a Denver Police officer.
The protests caused traffic delays in the area of Colfax Avenue and Mariposa Street. They were over by around 5 p.m.
Officers were able to scrub off much of the paint that was splattered over the memorial.
