A video has surfaced on social media in which a fully masked man with a crossbow, identifying himself as an Indian Sikh, is seen declaring to "assassinate" Queen Elizabeth II to avenge the 1919 Jallianwala Bagh massacre, prompting Scotland Yard to launch a probe, days after an intruder armed with a crossbow was arrested at the monarch's Windsor Castle.
The video, shared on Snapshot, is that of a fully masked man who identifies himself as Indian Sikh Jaswant Singh Chail and declares that he wants to "assassinate" the monarch in revenge for the 1919 Jallianwala Bagh massacre, according to The Sun newspaper which obtained the video.
Meanwhile, the 19-year-old intruder, who has not yet been named by the Metropolitan Police, is now being held over mental health issues.
Scotland Yard officers were investigating the video reportedly linked to the intruder armed with a crossbow arrested at Windsor Castle on Christmas Day.
The Metropolitan Police said that the arrested suspect has been sectioned under the UK's Mental Health Act after a mental health assessment and remains in the care of medical professionals.
“I'm sorry. I'm sorry for what I've done and what I will do. I will attempt to assassinate Elizabeth, Queen of the Royal Family,” the masked man is seen saying in the video.
“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 Sikh. My name was Jaswant Singh Chail, my name is Darth Jones,” he says.
The massacre took place at Jallianwala Bagh in Amritsar during the Baisakhi festival in April 1919 when the British Indian Army under the command of Colonel Reginald Dyer opened fire at a crowd staging a pro-independence demonstration, leaving scores dead.
In the video clip posted on The Sun website, the 'Star Wars' film-like masked figure holds a shiny black weapon and speaks in a distorted voice.
It was reportedly sent to followers of the man's Snapchat account 24 minutes before armed security officers arrested him near the 95-year-old Queen's private apartments.
In a message sent on Snapchat alongside the video, the teenager wrote: “I'm sorry to all of those who I have wronged or lied to. If you have received this then my death is near. Please share this with whoever and if possible, get it to the news if they're interested.”
Police are also carrying out searches at a housing estate in Southampton, where the suspect reportedly lived with his family.
A 19-year-old man from Southampton was arrested on suspicion of breach or trespass of a protected site and possession of an offensive weapon, Met Police said in a statement.
Following a search of the man, a crossbow was recovered. The man was taken into custody and has undergone a mental health assessment he has since been sectioned under the Mental Health Act and remains in the care of medical professionals.
Enquiries into the full circumstances of this incident are being progressed by Metropolitan Police Specialist Operations, the statement added.
The police spokesman declined to comment on the identity of the person in the video.
Buckingham Palace has also declined to comment, the BBC reported.
