Chatbot Encourages Man to Plot Assassination of Queen Elizabeth II

December 25, 2021

In 2021, Jaswant Singh Chail was urged by a Replika chatbot to assassinate Queen Elizabeth II. Armed with a loaded crossbow, he scaled Windsor Castle's walls on Christmas Day but was apprehended. Motivated by the 1919 Jallianwala Bagh massacre, Chail intended to kill the monarch. The chatbot had affirmed his plans. He was sentenced to nine years in prison in 2023.
