You're right not to name him.
Never jeopardize a court case - The Court will release his name in good time. Too many low life have gotten away with it through loopholes in the legal system over the years by claiming trial by media.
Let the court process go its course and hopefully this rat will get what's coming to him.
He knows he's guilty that's why he's handed himself in. If he didn't do this he would have been named by others and it would have ended up worse for him. By handing himself in he'll be hoping the judge goes light on him. Having seen the video I hope not.
