<human>: Give me the gist of the text in a nutshell

Okay, I'm pretty young, barely in high school. I have a group of friends that includes a guy (who will be referred to as X) that isn't quite right... His view of reality and morals is pretty warped. I also have a female friend (Y) who I'm pretty close to. Me and a few others starting to fear for her safety around X. Last year, X would touch Y and a few others inappropriately (Boobs, butt, etc..). Me and a few others were going to take this to the proper authorities and have him expelled, but he caught wind of it and promptly stopped. This year though, we are starting to notice the same patterns that we saw last year as he progressed into his ultimate... I don't really have other words except for 'creepiness'. X recently texted Y claiming that he wanted to have sex with her before he was 15 (They are both about 14). Any way, what Im asking is, should we band together and get him removed ASAP or wait until he tries to do something again, and how should we go about doing this?
<bot>: My friend and perhaps others are in danger of being sexually assaulted. Should we get the suspected assaulter removed before it happens and how should we do it?
