That month, Counter Terrorism Policing East Midlands shared information with MI5 who opened an investigation into Rhianan, and on 20 October 2020 police decided not to arrest her because it was "believed to risk some impact on her mental health" and "could possibly lead to further self harm and suicide attempts", the court heard.
The court was told that WhatsApp messages sent by Rhianan were contained in a student incident statement in September 2020, saying she "wants to kill someone in the school or blow up a Jewish place of worship" and that she "does not care who she kills and nothing matters anymore".
Rhianan's mother wrote in a 7 September 2020 email to the Home Office counter-terrorism programme Prevent that the teenager had a "massive dislike for certain races", counsel to the inquest Edward Pleeth said.
Chief coroner Judge Alexia Durran said the scope of the inquest includes how Rhianan's risk of self-harm and suicide was acted upon, such as the circumstances leading up to her charges being dropped, and how her care and support was coordinated.
Rhianan Rudd was a victim of grooming by a "neo-Nazi" American extremist who had "encouraged her to read some books" about Jewish and black people, Chesterfield Coroner's Court heard.
