Police released this surveillance video clip of a fight at Zan nightclub in downtown Springfield in April. Police arrested three people as the disturbance broke out downtown. Officers helped get the combative individuals outside, and police say, due to the officers feeling that their safety was in jeopardy, they called for backup. Springfield Police say hundreds of people gathered at the scene on Patton Alley near McDaniel Street and multiple members of the crowd were yelling profanities and threatening officers. SPD says officers began to yell, asking them to disperse for everyone's safety, but the crowd continually refused to obey verbal lawful commands.
