Rapper 21 Savage was arrested by U.S. immigration officials on Sunday, who said he was illegally in the country and a convicted felon.

The rapper, whose real name is Sha Yaa Bin Abraham-Joseph, came to the United States from the UK as a teenager in 2005, overstaying his visa to settle in Atlanta, said Bryan Cox, a spokesman for U.S. Immigration and Customs Enforcement (ICE).

Cox said Abraham-Joseph, whose 21 Savage Facebook page shows several upcoming concerts, was in custody in Georgia and faced deportation proceedings in federal immigration courts.

Abraham-Joseph’s lawyer, Dina LaPolt, said that the rapper’s team is

“working diligently to get Mr. Abraham-Joseph out of detention while we work with authorities to clear up any misunderstanding. Mr. Abraham-Joseph is a role model to the young people in the country — especially in Atlanta, Georgia and is actively working in the community leading programs to help underprivileged youths in financial literacy.”
