Young Thug's nephew Fardereen Deonta Grier was arrested in East Point, Georgia earlier this week.

But it has nothing to do with the State's RICO case against Thugger and all of his YSLs.

Grier has been charged with the murder of his girlfriend Destiny Fitzpatrick.  Officers responding to a call of shots fired found Fitzpatrick in a pool of blood by the front door of Grier's home.  Grier was in the home crying

Grier initially concocted a wild story about fending off two masked intruders.  However, he eventually admitted he had simply shot his girl in the face.

Throughout his arrest, Grier kept mentioning that Thugger was his uncle.

Thug has ten siblings, so he has many nephews.
