A man who was arrested on the grounds of Windsor Castle with a loaded crossbow pleaded guilty to treason on Friday for planning to attack Queen Elizabeth II. Jaswant Singh Chail, 21, admitted to a charge under the Treason Act of intending to “injure the person of Her Majesty Queen Elizabeth II, or to alarm her Majesty.” Chail appeared at London’s Central Criminal Court by video link from Broadmoor, a secure psychiatric hospital where he is detained.
