Boulder police officers responded to a large fight near the Shooters bar at 13th and Walnut streets around closing time in the early-morning hours of Feb. 28.
It appears several patrons left the bar and began fighting outside. Officers arrested one person as a result of the investigation.
The suspect, a 29-year-old Longmont man, is facing charges of distribution of a controlled substance after officers reportedly found Ecstasy pills and cocaine on him.
No one required medical attention.
