Another meeting with Henry's daycare

We need to meet with Henry's daycare again. I have no idea what to do. Henry just doesn't care about anyone but himself. If he feels like hitting you than that's what he'll do. It doesn't help that he's got a "reputation" now. Everything he does now is magnified and the kids know they can set him up or get him in trouble easier. The teachers know it but no one knows what to do. He's got little impulse control and he's getting frustrated which makes it worse. I'm worried and I just don't know what to do.
