CHICAGO (AP) — Authorities say an attack in Chicago that wounded five people was likely in retaliation for one earlier this week in which an aspiring rapper and five other people were shot at a funeral.

Chicago Police Department spokesman Anthony Guglielmi said Friday that there’s a “high probability” that the Wednesday attack in the Washington Park neighborhood is connected to Monday’s funeral attack in Burnside.

Both neighborhoods are on the South Side.

Disputes between the Black Disciple and Gangster Disciple gangs have long underpinned violence in the neighborhoods.

Taunts on social media and in raps songs help fuel tensions.

Police had warned that retaliation was likely after the attack in which 21-year-old rapper Marvel “FBG Wooski” Williams was shot in the head. He was in stable condition Monday after surgery.

In his song, “Computers Remix,” denounces rivals while flashing gang signs.

There have been no arrests in either shooting.
