<human>: At my old middle/high school, I've heard from a couple different people about an incident last month where two 8th grade boys were sleeping over at a friend's house. They got mad at him, and somehow ended up locking his little 6th grade sister in a room and sexually assaulting her. The police were called, the school was involved, and the boys expelled and facing possible legal action. I heard the story a month ago, but I was talking with another friend of mine yesterday when she revealed that one of the boys involved is my neighbor.

I have another neighbor with girls who are the boy's age and younger. They go to another school and have no idea about any of this. The girls are friends with the boy's twin sister and  him, and they often go over to each other's houses. I'm worried about their safety. I really feel that their parents should know about this. However, everything I have heard has come second-hand. I don't want to spread gossip like this if there is even the tiniest chance it is untrue. The stories are all remarkably consistent though, and I know that the boy in question did leave the school this month, supporting what I've heard.

Can you give me a shortened version of the text?
