London: A 51-year-old Bulgarian threatened to assassinate Princess Diana`s former butler Paul Burrell and also his sons and brother, a media report said.
Slav Mitev, who made threatening calls to the butler, and also claimed to have kidnapped his wife Maria, has been ordered by a court to never again contact him, the Daily Express reported.
The Chester Crown Court heard Mitev, of Wood Green, London, twice threatened to set fire to the Burrell family`s florist shop in Farndon, Cheshire.
He has been sentenced to a two-year supervision order after it was agreed he did not need to be detained in hospital.
The man was deemed not mentally fit to enter a legal plea, but a social services report suggested he be monitored by a social worker in London.
He must remain at his home address for the duration of the order.
Burrell said he was subjected to a number of calls that caused him real distress.
Diana`s ex-aide said he knew no reason why Mitev launched his campaign in June 2011.
