<human>: Condense the text into a few key points

Hi there,

So my sister is a ballet dancer, almost 2 years ago a new male teacher joined the faculty of the academy she was dancing at, this would make her 17 at the time. This male teacher (let's call him John) was a fantastic mentor for my sister and she often had private lessons with him. This is completely normal in dance studios all over the country. About a year and a half ago, some of my sister's "friends" got the idea into their heads that my sister and John were sleeping together. Despite denying this repeatedly, these fellow students got their parents involved and even confronted my mother about this. My mom completely denied this, as did my sister; I was unaware that this was occurring at the time. John remained a family friend as we really appreciated all the effort he has put into my sister's career, he would sometimes come over for dinner or join us for outings. This summer he taught my sister a fair bit but rarely at the dance academy where these lies started. My sister has spend the past year living abroad and we thought this whole situation had died down but apparently this is not the case.

This morning I awoke to find that John has been taken into custody for charges of sexual exploitation and luring. Luckily, my sister (now almost 19) is working in Europe at this time and none of her information was released due to her age at the time of the alleged charges. I am also working in Europe, so my mother is the only one left in our city. I am unsure how to proceed or what I can do about this whole situation. I 110% know these allegations are based on lies and suspicions, but at the same time I don't want my family to be dragged into the public eye about this. I have contacted my mother and am waiting to hear as to whether the police have contacted her yet.

Any advice would be much appreciated.
