The youngest girl in Britain to be charged with terror offences killed herself at children's home after being groomed and radicalised by two convicted American neo-Nazis, a coroner ruled.

Autistic Rhianan Rudd, 16, plotted to blow up a synagogue and scratched a swastika into her forehead after coming into contact with the two men, one of whom was dating her mother and moved into their Derbyshire home.

Rhianan was found dead at Bluebell House children's home near Newark, Notts, on May 19, 2022, five months after terror charges against her were dropped.

A four-week inquest into her death heard how Dax Mallaburn, a violent US neo-Nazi with a swastika tattoo on his forearm, moved into the family home in Clowne, Derbyshire, in 2017 after forming a relationship with Rhianan's mother Emily Carter via a prison pen-pal scheme.

Chesterfield Coroner's Court heard Rhianan was also in contact with Christopher Cook, from Ohio, with whom she exchanged explicit photographs. Cook, 23, a member of the banned terrorist group Atomwaffen Division, was jailed in the US in 2023 over a plot to attack power grids.
