Other children’s behaviour

At preschool there is one boy who hits a lot and the other children have labelled him as the naughty boy. My little girl loves playing with the noisiest child she can find so is often playing with this boy. However every day she tells me he’s hit her, trapped her somewhere, covered her in a blanket etc and she says she tells him to stop it, they’ve taught the kids to say my voice matters and I know my little one is very vocal if she doesn’t like something but he doesn’t listen then she ends up crying until a staff member rescues her. The staff there never tell me any of these things happen. Is that normal? Would you be having chats asking someone to supervise their play better? Ideally she wouldn’t play with him as she always says he’s mean to her because she’s a girl too 🙈 but obviously she needs to work that out herself. Other mums say their girls have had similar issues but they have stopped playing with this boy..
