Spawned for me on the arena floor this morning. I killed "a veteran" just before the spawn, not sure if this is a PH or not. Dropped 3 loots, all pretty nice.
He definitely is leashed to the south end of the arena floor, if you try to move him away he will warp back to his spawn loc (and sometimes return to full HP). The good news is you can easily get him single by rushing him when the wanderer near him walks away. A single group with a good tank/healer can handle this hero (sorry didn't log specific numbers, just know 5 os us killed him twice in a few hours).
Update - While he warped back first two times we killed him, we have since been able to pull him to other end of arena no problem. So either he changed or we didn't pass the leash boundry on the last few tries...
With leashed mobs, if you keep them kinda close to the puller they will continue to pursue the puller. You should be able to get him to the other end if you do not outrun him too much.
