Officials say Scrappy violated his probation back in March after a dispute over a pee test. According to court officials, Scrappy tried to turn in a urine sample that was cold to the touch and may have been tampered with ... and when asked to submit another cup, he refused.
The court eventually issued a warrant for his arrest ... and moments ago, the "Love & Hip Hop: Atlanta" star turned himself in.
Scrap was photographed walking hand in hand with his fiancee Erica Dixon on his way in and his mother, Momma Dee ... who was already sporting a "Free Scrappy" shirt.
Naturally, the VH1 cameras captured the dramatic moment on tape.
