II don't know if I should speak to the police about this so would be grateful for any advice or views.
DS came out as trans M2F a few months ago so I will use female pronouns when talking about her. It's not relevant to the story but didn't want to get mixed up. She is also potentially on the ASD spectrum although we are on a waiting list for a diagnosis.
A couple of weeks ago a family friend alerted us to an Instagram page she had set up in secret. It's urban exploring. She has basically been going out to meet friends but has actually been in old burnt out abandoned buildings, railway lines, climbing pylons... we sat down and had a very long chat about how dangerous it was and she agreed she would stop.
Today she refused to go to school (this had been ongoing for 2 years and we are at about 45% attendance. I went to work as I had meetings I couldn't reschedule but removed all internet access from her phone as a consequence for refusing to get up. When we got home she had been using her younger sisters tablet and had left herself logged into this Instagram account. I've read messages organising a meet-up this weekend, she has told all her friends to turn up in black clothes, bring balaclavas and grippy shoes because the location is "very slippy" and asked who can access spray paint.
WIBU to contact the police tomorrow?? If I did are they likely to do anything?? We are in a very precarious position with very poor mental health, refusal to engage with GP or CAMHS, sort of engaging with a Barnados key worker at the moment but she has a habit of attacking me and running away if we try to discuss anything with her.
