Ty Dolla Sign has been indicted on felony charges of cocaine and marijuana possession, TMZ reports and documents viewed by Pitchfork confirm. The charges could lead to a prison sentence of up to 15 years, according to TMZ. The indictment includes two felony charges—possession of a Schedule 1 controlled substance and possession of cocaine—and one misdemeanor charge, for possession of less than one ounce of marijuana.

Ty Dolla was arrested and detained in September in Atlanta after officers searched his vehicle, claiming they smelled marijuana. Skrillex and several others were also in the vehicle, but police pressed charges only against Ty, TMZ reports.

A representative for Ty Dolla Sign told TMZ, “[Ty] understands from his attorney Steve Sadow that the indictment in Fulton County, Georgia is merely the next mandatory procedural step in the process of resolving Ty’s case in that particular criminal justice system, and one more step closer to finally bringing this matter to a close. It was expected by Ty’s legal counsel and came as no surprise whatsoever.”

The rep reportedly continued, “Ty maintains his innocence and there is no indication to the contrary. It’s also very important to note that Ty’s jewelry and cash seized from him upon his arrest in September 2018 was ordered returned to him last week... another clear sign that this matter is coming to a close soon.”

Pitchfork has reached out to Ty Dolla Sign’s reps for comment.
