Chief Keef has been charged with a DUI following his detainment in Miami Beach Saturday, according to TMZ. As previously reported, Keef was cuffed and brought in for questioning after cops pulled him over. The stop was made for what the officers believed to be an exchange of weed made by a passenger in the rapper's car with those in the vehicle behind his.

Later on, Keef reportedly failed a sobriety test, and was therefore charged with a DUI. He is said to have told police, "It's okay. When you find weed in my urine I'll just get my attorney to get my marijuana card."

The report suggests that "weed and other substances" were found in the car trailing Keef's. A cup of lean was also found by cops, though it is not specified which car it was taken from. 4 people were charged with misdemeanor possession of marijuana.

Keef released a video for his new song "Kills" Saturday. Watch it here.
