The school claims there is more to the issue. However, due to “data privacy reasons” the school is unable to release any details that would either vindicate their actions, or give more information about the incident. Here is a link to the message the principal sent to families about the social media posts and the incident. In the letter the principal states that no students are barred from using any restroom at the school.
There are videos of the incident in each of the CBS articles.
