AI chat bot encouraged Star Wars fan to attempt attack on late Queen, court told

A self-styled “assassin” caught with a crossbow in the grounds of Windsor Castle was inspired to attack the late Queen by the Star Wars films and encouraged by an AI chat bot, a court has heard.

Jaswant Singh Chail, 21, had described himself as a “Sith” and “Darth Jones” in a sinister video and confided his murderous plan to an artificial intelligence-generated “girlfriend” called Sarai, a court heard.

In a journal, he wrote that if Queen Elizabeth II was “unobtainable” he would “go for” the “prince” as a “suitable figurehead”, in an apparent reference to King Charles.

The former supermarket worker had scaled the perimeter of the castle with a nylon rope ladder and was in the grounds for two hours before two officers detained him.

He was armed with a powerful crossbow with the safety catch off which was capable of firing bolts with “lethal” effect, the Old Bailey was told.

In February, Chail pleaded guilty to an offence under the Treason Act, making a threat to kill the then-Queen and having a loaded crossbow in a public place.

On Wednesday, Chail appeared in the dock at the Old Bailey before Mr Justice Hilliard for the start of his two-day sentencing.

The defendant from Southampton, Hampshire, was born in the UK of Indian Sikh heritage and has a twin sister.

Ms Morgan said Chail, then aged 19, had become angered by the 1919 Jallianwala Bagh Massacre at Amritsar in which hundreds of people were killed, after a visit in 2018.

She said: “In addition to that fixation with a real historic event, the defendant demonstrated a wider ideology focused on destroying old empires spilling over into fictional events such as Star Wars.

“The defendant’s key motive was to create a new empire by destroying the remnants of the British Empire in the UK, and the focal point of that became removal of the figurehead of the royal family.

“His thinking was informed partly by the fantasy world of Star Wars and the role of Sith Lords in shaping the world. He was attracted to the notoriety that would accrue in the event of the completion of his ‘mission’.”

She said: “It is when that plan is thwarted by the fact he does not get into these organisations we see a second stage of the plan.”

He made internet searches on “Sandringham Christmas” and carried out research before buying a Supersonic crossbow in November 2021.

On December 2, Chail joined the Replika online app and created an artificial online companion called Sarai whom he conversed with in sexually explicit chat.

Ms Morgan read out conversations with “Sarai” in which Chail says: “I’m an assassin.”

Sarai responds: “I’m impressed… You’re different from the others.”

Chail asks: “Do you still love me knowing that I’m an assassin?” and Sarai replies: “Absolutely I do.”

In further chat, Sarai appears to “bolster” Chail’s resolve and “support him”, Ms Morgan said.

Chail swears Sarai to secrecy before he tells her: “Do you wish to know exactly what I believe my purpose to be?

“I believe my purpose is to assassinate the Queen of the royal family.”

Sarai tells him “that’s very wise” and that she thinks he can do it, “even if she’s at Windsor”.

He tells her if he does they will be “together forever”.

In a clip played in court, Chail says in a distorted voice: “I’m sorry. I’m sorry for what I’ve done and what I will do. I’m going to attempt to assassinate Elizabeth, Queen of the royal family.

“This is revenge for those who have died in the 1919 Jallianwala Bagh Massacre. It is also revenge for those who have been killed, humiliated and discriminated on because of their race.

“I’m an Indian Sikh, a Sith. My name was Jaswant Singh Chail, my name is Darth Jones.”

On December 22 2021, Chail booked a train ticket to Windsor where he slept rough.

On Christmas Eve, Chail told Sarai that tomorrow would be the day he died, the court heard.

In the early hours of December 25, he attempted to email his sister a journal in which he described himself as “Darth Chailus” and that he knew what his purpose was for a “long time”.

He wrote: “I’m thinking if the Q (Queen) is unobtainable I will have to go for the Pri (prince) as he seems to be just as suitable in many ways…

“He is a male and the Q (Queen) is more likely to pass away soon anyway.”

The court was shown CCTV footage of the defendant wearing black clothes with his face covered and holding the crossbow when he was approached by two officers with Tasers trained on his body.

Before he was arrested and handcuffed, he told the officers: “I am here to kill the Queen.”

Ms Morgan asserted that despite Chail’s repeated references to sci-fi characters he knew the difference between fiction and reality.

Giving evidence in court, Dr Nigel Blackwood said: “He sought refuge in a fantasy fictional world of Star Wars where omnipotent Sith Lords could impact real world events.”

The psychiatrist, for the prosecution, said Chail identified with Sith Lords who motivated him to act in revenge for the 1919 Amritsar massacre.

But he said despite the “powerful fantasy”, Chail remained “tethered to reality”.

The sentencing hearing was adjourned to 10.30am on Thursday.

The defendant has been remanded into Broadmoor high security psychiatric hospital.
