Last week R. Kelly was hit with 13 new federal charges of child pornography [click here if you missed that].
Apparently the new tapes came from his former inner circle...
From TMZ
Gerald Griggs -- who represents Joycelyn Savage's family among others -- tells TMZ the federal investigation run by the Northern District of Illinois uncovered over 20 videos of Kelly engaged with minors.
Both Griggs and our federal law enforcement sources tell us the tapes show multiple victims ... and prosecutors confirmed with multiple witnesses the girls were underage. Griggs says several of Kelly's enablers -- past and present -- flipped and turned over the tapes to investigators. He says those videos were exactly what the feds needed to secure indictments for sex crimes, including child pornography.
