Doesn't look like it's be any of the really "big" Soap names based on what's been said, mentioning role(s) plural and saying he's worked with some of the biggest stars, suggest it's not a "life-long" household name soap star (like an Ian Beale or Phil Mitchel etc.). If it was a household name it would be huge news. If it's someone who has been in a few big temporary character roles then not so much. Though the severity of the crimes is no different, obviously.
