The 19 year old planned a Stop The Violence gig in his hometown on 17 July (15) to benefit his friend and fellow rapper Capo, who was shot and killed.

Chief Keef chose to perform at the gig via hologram instead of risk returning to the Chicago area, where he has outstanding warrants for his arrest related to separate child support cases.

However, just before the show was slated to start, Emanuel's office cancelled the concert amid fears it posed a "significant public safety risk."

The rapper refused to back down and opted to stage the gig at nearby Hammond, Indiana's Craze Fest, again via hologram from Los Angeles, on Saturday (25Jul15).

But yet again, police shut down the event shortly after the rapper "appeared" on stage, and Keef took to Twitter.com on Monday (27Jul15), encouraging his fans to call the mayor's office and urge him to let the concert go on.

He wrote, "Call Mayor of Chicago @rahmemanuel... and tell him to stay the f**k off the people's music #StopTheViolenceNow."

Keef later told his fans that instead of changing Mayor Emanuel's mind, he will just run for office instead, adding, "I'm running for mayor of Chicago... Vote for me!!!! It'll be the best thing done yet!!!!! Yall gonna love me in the Office..."
