The criminal charges against US musician and actor Yasiin Bey, also known as Mos Def, have been dropped by the Department of Home Affairs and he was due to fly out of South Africa last night. He was charged after trying to leave the country without a valid passport earlier this year.Born Dante Terrell Smith, Mos Def was arrested in January in Cape Town when he tried to leave South Africa using a "World Government of World Citizens" passport. The World Government of World Citizens was established in 1953 by peace activist Garry Davis, who renounced his US citizenship after World War 2. He died in 2013.Mos Def reportedly entered this country with a US passport and his visitor's visa was valid until February. His family's visas allegedly expired in 2014 and he was accused of helping them to stay in this country illegally.The musician appeared in the Bellville Magistrate's Court on charges relating to contraventions of the Immigration Act.He has apologised for his conduct."Mr Smith/Bey will be declared an undesirable person ... in terms of Section 30 of the Immigration Act of 2002," said Home Affairs director-general Mkuseli Apleni."He will, therefore, not qualify for a port of entry visa or admission to the republic."Based on his apology and the confirmation that he will depart on [Tuesday night] using a valid passport, the department will withdraw the charges against him." - TMG Digital..
