Further to an earlier post about spinning black holes, it appears that the blackhole in our own glalaxy is more massive that previously thought (between 3.2 million and 4 million solar masses) and is rotating at an incredible rate , once every 11 minutes or at about 30% of the speed of light.

And, yes, frame dragging seems to be involved as well, distorting the space-time around it in a way enabling matter to orbit it at far higher speeds than would normally be expected. [link]
