The Aogiri Arc starts in chapter 47. The anime skipped an enormous amount of material, so you're best starting at the beginning since it develops Aogiri as well as Kaneki's relationship with Banjou's group prior to the whole torture stuff. There's also considerably more development for Juuzou and Shinohara.
