Moment armed police arrest TikToker poking his microphone under nose of King’s Guard horse and its rider – and he’d previously been held outside Downing Street too

A TikToker who posts videos of himself rounding up police outside Buckingham Palace has been arrested after shoving his microphone under the noses of a King’s Guard and his horse in London.

The prankster, known by TikTok handle ymusa18, was handcuffed and led away after he started confronting people who criticized him for harassing the security guard and his horse as tourists tried to take photos on Thursday.

Like Mizzy, the law-breaking prankster who has since vowed to change his behaviour, the prankster films himself harassing members of the public – and was searched outside Downing Street for appearing to suggest he was carrying a bomb.

But in his latest stunt outside the Household Cavalry Museum in Whitehall, he confronted members of the public who hated his pranks – and was then grabbed by armed police and tied to a fence as he begged them for calm.

Multiple angles of the incident have been shared online – including by the fame-hungry prankster himself – after it happened earlier this week.

Calling it ‘interviewing the Royal Guard and their horses’ in his own version of the clip, the joker holds a microphone to the horse’s snout and asks its name as he walks right through a bewildered tourist posing for a picture.

He is filmed the entire time by a friend, who remotely captures the footage for the TikTok video.

The Royal Guard maintains a professional facade throughout, even when the prankster hits him with nonsensical questions about riding the horse – but eventually members of the public grow tired of his antics and call him out.

“Don’t be so damn rude. Fuck off, you rude bastard,” said one man, identified by MailOnline as a YouTuber who regularly takes videos of tourists outside the museum.

Another audience member, realizing that ymusa18 is filming the video for an online prank, then moves to cover the lens and disrupt the video – which outrages the young TikToker, who approaches him and says: “That’s my phone, man, you can’t touch it. That.”

“Go on, p*** off,” says the earlier YouTuber – to which the youngster replies: “Say that to my face.”

“P*** off,” the videographer says again, pushing the prankster back when he gets too close for comfort.

The angry TikToker then goes into a tirade, yelling over and over, “Who the fuck are you touching?”

As he shouts at the cameraman, two armed police officers, a man and a woman, come running out of the museum gate, clutching machine guns.

The male officer places his hand on the prankster’s chest, pushes him back and sternly announces, “Go back.”

His pranks are similar to those of Mizzy (above), who has since renounced his buffoonery after being convicted of several offences.

The prankster is quick to protest: ‘I didn’t do any s***, I didn’t do any s***, didn’t you see what happened, mate? I’m calm, I’m calm, no need to grab my neck, bro, no need to grab my neck. I didn’t threaten anyone, you know.’

When he is told that he is being arrested on suspicion of a public order offence, he stops talking – and remains silent as he enters the gates of the museum.

In his own clip, as he is taken into the compound, he flashes a grin at the camera.

What is the Kingsguard and what are the rules surrounding it?

The King’s Guard is the name given to the group of soldiers responsible for guarding Buckingham Palace and St James’s Palace.

Traditionally, guards stand still for two hours during their guard duty, before taking a four-hour break.

Every 10 minutes they come to attention, raise their arms and march 15 steps across the area of ​​the pole.

The Kingsguard are generally not allowed to interact with the crowd, but may shout or present bayonets if they get too close.

The soldiers must allow nothing to distract them from their duties – with toilet breaks banned during shifts – and will march through anyone who gets in their way.

In common with other parts of Whitehall and rural locations of utmost national security, the Household Cavalry Museum is protected by the Ministry of Defense Police rather than the Metropolitan Police.

MailOnline has contacted the Ministry of Defense for comment.

Ymusa18’s TikTok shows him harassing the public on trains, pretending to fall asleep among passengers.

He also pulls off what he calls “Uber pranks,” climbing into the backs of police vehicles as if they were taxis – much to the annoyance of the officers inside.

But his other ‘jokes’ put him in much greater danger – including outside Downing Street, where, in full view of armed police, he said: ‘Rishi Sunak, I have a message for you. If I see you on the street, there will be trouble, you understand?’

He adds: ‘You little minions, they won’t do anything about it’ – just before an armed police officer opens the gate and tells him to behave.

Some time later he is led away by police further down Whitehall after apparently suggesting he had an explosive in his bag.

“You tried to say you had something in your bag,” a police officer is heard saying. “You mentioned C4 (a plastic explosive).”

The video ends with him leaving Charing Cross police station and boldly proclaiming: ‘Yes guys, I’m free now. The police can’t detain me. What have I done? I’m innocent, yes?’

He also dared police to arrest him after he crossed the threshold of the Buckingham Palace gates in front of armed officers, who told him: “Don’t push your luck.”

In a subsequent video, he promised to climb the gates of Buckingham Palace if the clip received 5,000 likes, a figure he later adjusted to 15,000. There are now 36,000.

“Get me to 10k and I’ll post more serious (videos),” he says in his bio.
