Eyeless Jack

guys, me and my friend are being stalked, so..a boy in my class named Alex has been following us since the start of the year, he touches us when we say not to, we checked, the way he touches is a form of SA, he touches our legs, thighs, back, heads, and faces, without consent and chases us when we run, he also watches us even when the teachers tell him to stop, he follows us, and even got Spotify to follow me and my friend to track us, he always looks at our stuff and he tried to out me as trans to the class, he cried when we told the teacher what he's done, then today, he watched us again. he kept following us to the point we couldn't do our work, we moved desks, but on my way home, he waited for me..his phone pointed at me his head tilted, until everyone else had left, I looked away for a moment, when I looked back he was gone, then while my mom drove me home, he walked away from where he said he lived close to my car..I'm scared and don't know what to do anymore, I guess what I'm asking for is advice.. me and my friend googled symptoms of stalking and SA offenders, he checked every single box...and he hangs out with kids much younger then him, and he pulls them down, I'm worried, this isn't even a talkie, I'm talking about real life...help me.. please
