Viral Video: Indian Sikh declares to assassinate Queen Elizabeth II

A probe is set to arrest the masked man.

London: Viral video surfacing on the internet in which a fully masked man with a crossbow identifies himself as an Indian Sikh, who has been seen declaring to "assassinate" Queen Elizabeth II to avenge the 1919 Jallianwala Bagh massacre. A probe has been prompted to be set by Scotland Yard days after an intruder armed with a crossbow was arrested at the monarch's Windsor Castle.

According to the report of The Sun newspaper, the viral video comes from a Snapchat story of a masked man, identifies himself as Indian Sikh Jaswant Singh Chail and swears that he wants to "assassinate" the monarch in revenge for the 1919 Jallianwala Bagh massacre.

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 investigating the video reportedly linked to the intruder armed with a crossbow arrested at Windsor Castle on Christmas Day.

According to the investigation of the Metropolitan Police, 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".

The visuals coming from the viral video says, "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 also added, "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 against because of their race. I'm an Indian Sikh, a Sikh. My name was Jaswant Singh Chail, my name is Darth Jones."

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. "Enquiries into the full circumstances of this incident are being progressed by Metropolitan Police Specialist Operations," the statement added.

In a report of BBC, Buckingham Palace has also declined to comment.
