Chief Keef Arrested For Weed In Atlanta

According to the police report, obtained by TMZ, Keef was busted for allegedly smoking weed at a fancy hotel.

The booking sheet, Keef -- real name Keith Cozart -- was listed at 5'9" and 160 lbs.

After the arrest, Keef tweeted, "Jus Got Out Of Dekalb County jail In Atlanta Mad As f**k."

Keef is considered a prodigy -- and has rapped with huge stars like 50 Cent and Wiz Khalifa.

Keef is no stranger to the law ... he's been arrested at least two times before -- and even has a gun conviction under his belt.

It's been a rough year for the rapper ... he was recently sued for child support by his middle-school-aged baby mama who claims Keef fathered her kid -- born in 2011 -- when he was only 15.

This ni**a always gettin' arrested! You would think with the nice a$$ deal Interscope gave him he would just make music & be easy!
