It all went down at a pick-up basketball game when the rapper allegedly threatened to kill another player who just happened to be a cop
TMZ broke the story … an arrest warrant was issued last week when the D.A. charged Game with one count of making criminal threats back in March.
Law enforcement sources tell TMZ … the rapper surrendered to LAPD just after noon on Monday, and was released 54 minutes later — once he posted his $50,000 bail.
Meanwhile, Game posted a photo chilling in a hot tub on Sunday, saying … “Relaxing in the sauna before I turn myself in….. But what you gon’ do when you get outta jail… I’m gonna have some fun.”
