And celebrities and fans are sending messages of support to Grammy-nominated rapper 21 Savage, who was detained by agents from Immigration and Customs Enforcement on Sunday. ICE says British-born Shéyaa Bin Abraham-Joseph, better known by his stage name 21 Savage, overstayed his visa after coming to the U.S. at the age of 12 in 2005. A “Free 21 Savage” petition, created by Black Lives Matter co-founder Patrisse Cullors, has so far gathered over 200,000 signatures. Lawyers for the rapper say he is being wrongfully detained and that his new visa application is currently pending.
