Brooklyn-born rapper Yasiin Bey, still best known as Mos Def, has been in the headlines for all the wrong, non-music-related reasons lately. The 42-year-old performer and actor was arrested recently for allegedly violating South Africa’s immigration laws, presenting an invalid passport, and trying to keep his family in the country through illegal means. Currently out on bail, Bey will have to appear in court to face these charges on March 8. His family will have to leave the country by January 29. For his part, Bey maintains his innocence and claims to be baffled and frustrated as to why the South African government is harassing him. He expressed these feelings in the form of an a cappella freestyle rap that has been posted to the website of fellow rapper Kanye West. And in light of these troubling events, Bey announced his retirement “effective immediately” from the music business. After one final album, he says he’s done.
