Ten people, including an alleged suspect, were wounded during a shooting in Denver while a crowd was celebrating the Nuggets winning their first NBA championship.

Three of the people were critically injured, which was confirmed by the Denver Police Department. The suspect, an unnamed male, was one of the seven people with non-life-threatening injuries. Police haven’t released a lot of information surrounding the shooting, but it is believed that the incident started with an altercation that led to gunfire.
