Lil' Flip was in the middle of a rendition of "Riding Spinners” at the 4/20 rally at the Civic Center Park in Denver, CO yesterday when two men began shooting into the crowd.

According to a report from Denver’s 7News, the scene turned into mass panic as thousands of concertgoers scurried to get out of harm's way.

A man and a woman were shot in the leg and a juvenile was sent to a hospital after being grazed by a bullet. Other (less severe) injuries were sustained when the audience fled away from the stage and some people were trampled.

The investigation into the shootings was turned over to the Denver Department's Gang Unit today. Police are currently searching for two suspects.

While police have spoken with a number of witnesses, they have asked any person at the concert during the incident with video footage of the event to come forward.

Multiple roads in Denver are still closed off and all "4/20 pot-related events" at the Civic Center for the weekend have been cancelled as the investigation continues.
