i believe it was revealed in crookedstar's promise!

i don't really consider the dark forest training to be a viable reason to send someone there, given a lot of cats in the series did the same -- it's more likely he was sent there for killing a cat while training there (don't remember where it was shown but i believe the cat was houndtooth) and also condoning the harm of a kit (scourge). while all trespassers should be challenged, it was out of line for him to let tigerpaw attack him (and more so to be willing to let him severely injure him.)
