**UPDATE** December 18
The 100-count indictment includes gang activity, multiple shootings and drug trafficking.
Police found 20 handguns inside Quad City Studios where Bobby was picked up, according to 7 Online.
The rapper's lawyer says the charges are false.
"There is nowhere in the western world where he can go without being recognized," defense attorney Howard Greenburg said. "And you're telling me he has to take time out of his busy life as an entertainer and do what is alleged in this indictment? It's a bunch of BS, and you can quote me."
