Rapper Alfamega has been dropped from T.I.’s Grand Hustle imprint after The Smoking Gun released documents revealing that Alfamega was a Drug Enforcement Administration informant in the mid-’90s, providing key testimony that put at least one alleged drug trafficker in prison.

On Thursday, T.I. announcement that he was severing all ties with his one-time sidekick: “Even though all our artists and employees are asked by us to be honest and open about their past history, at no time did Alfa disclose to me or Grand Hustle what has now appeared in the media. He essentially deceived us by failing to fully disclose the truth about his past, and there is no place in our organization for dishonest and misleading behavior.”
