Police say members of the Bomb Squad gang were having a party in the 1600 block of N. Bigelow St.
Members of the Zone Four gang showed up to apparently "crash the party."
That's when officers say a fight broke out with weapons. Four to five shots could be heard by officers in the area.
Two people showed up at the hospital with injuries related to the fight.
Officers also made several stops once people tried to flee the scene. A shell casing was also recovered.
Police did not mention any arrests as of Saturday.
