I don't think he was ever named. Dmcdevit was the one who first sent the information to Arbcom, though it also seems he was in contact with the steward in question? I'm not entirely sure, it seems all a bit jumbled and a clear answer was never given, nor an apology (not surprising).
Feel free to
read the discussion about it on the Arbitration talk page archive.
