A week after shocking mass shooting outside River North lounge, links to city’s worst gang feud have surfaced again.

A crowd was said to be leaving Artis Lounge on Chicago Avenue following an album release party for rapper Mello Buckzz when three shooters opened fire.

At least seven people were injured in a shooting in Chicago’s Back of the Yards neighborhood Friday night. According to police, two male suspects approached a group of people who were standing outside in the 4800 block of South Justine at approximately 11:11 p.m. The two suspects then opened fire, striking multiple victims.

Four people were killed and 14 others wounded in a "deplorable and cowardly" mass shooting in Chicago on Wednesday night, according to the police superintendent.
