A Scotland Yard spokesman said: “Following the man’s arrest, detectives are assessing the contents of a video.”
What did he say?
In the clip, he can be heard saying: “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.
“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.”
What is the Jallianwala Bagh massacre?
Also known as the Amritsar massacre, it took place on 13 April 1919.
A large peaceful crowd had gathered to protest against the arrest of pro-Indian independence leaders.
In response, the British Brigadier-GeneralR. E. H. Dyer surrounded the Bagh with his soldiers. He then ordered his troops to open fire on the crowd, and estimates of those killed vary between 379 and 1500+ people.
Where and when was the video first posted?
According to The Sun, the pre-recorded clip was uploaded to Snapchat at 8.06am on Christmas Day, less than half an hour before the man was arrested by police.
Has the suspect’s family said anything?
Yes. His father told MailOnline:“Something’s gone horribly wrong with our son and we are trying to figure out what.
“We’ve not had a chance to speak to him but are trying to get him the help he needs.

“From our perspective, we are going through a difficult time. We are trying to resolve this issue and it’s not easy.”
Have the police turned their attention to his home?
Yes, the police searched the family’s home in Southampton.
One neighbour told The Sun: “There was a big commotion with all the police around and it caused some concern, especially as it was Christmas Day.
“The family keep themselves to themselves, like the rest of the estate, but we know there’s a teenage lad who lives there with his mum and dad. The police didn’t leave the estate until late at night.”
How serious was the latest threat?
Retired chief superintendent Dai Davies, the former head of royal protection at Scotland Yard, called it a ‘potentially tragic threat’.
He told MailOnline: “Since the time of George III, 99 per cent of attacks against members of the Royal Family have involved a fixated person, or stalker. And the news that a crossbow was involved actually scares me. They will go through a windscreen.
“And in all my years of crime and catching criminals, it is rare for crossbows to be used for criminal purposes.
“Anyone knowing the royals were in residence and having a fair idea of their comings and goings, could pose a very real and potentially tragic threat with something like that.”
What’s happened since?
Home Secretary Priti Patel has ordered a review of the current rules surrounding crossbow ownership. A Home Office spokesperson said in a statement the department has been instructed to look at possible ways to “strengthen controls” on the weapons.
“Crossbows are subject to controls and legislation is in place to deal with those who use them as a weapon,” the spokesperson said.
“At the Home Secretary’s request, we are considering options to strengthen controls on crossbows. Work on this has been ongoing throughout the year, and we keep all relevant laws under review to maintain public safety.”
