In order to prevent any more rumours from being spread, this is an official announcement from the trustees of Hogwarts as well as the administrators.
There have been two rapes on Hogwarts school grounds in the past several weeks, and the culprit has been found. Nathaniel Hedges (7th year, Slytherin) has been accused of one of the crimes, and has been arrested. Further investigations will take place. If you have any information about either rape, or have any other evidence or concerns, feel free to come speak with myself or any other professor. You can also leave me comments, and you can trust that any private comments will retain anonymity when I inform the ministry.
