YouTuber Adam Saleh was escorted off a Delta flight from London to New York

This is the shocking moment a YouTube prankster was allegedly 'kicked off' a Delta flight at London Heathrow for speaking Arabic.

Adam Saleh, 23, who has 1.6 million followers on the video site, was escorted off the flight to New York after an American female passenger heard him talking in another language and 'felt uncomfortable'.

The rapper and internet celebrity, who filmed the entire incident, was furious, later tweeting: We got kicked out of a @Delta airplane because I spoke Arabic to my mom on the phone and with my friend slim... WTFFFFFFFF please spread.'

Despite the dramatic video, many have questioned the authenticity of the online prankster's claims.

The New York internet star shot to fame through his prank channel, but has been forced to reveal that some of his biggest 'pranks' were actually staged.

Saleh was even forced to make a grovelling apology over his most infamous hoax - the anti-police 'Racial Profiling Experiment' video - that claimed US officers had abused him over his religion.

This is the shocking moment a YouTube prankster was allegedly 'kicked off' a Delta flight at Heathrow for speaking Arabic

Adam Saleh, who has 1.6 million followers on the video site, was escorted off the flight from London to New York after the airline says more than 20 other passengers complained about him

And just last week, he filmed a fake video of himself, supposedly flying to Sydney inside a suitcase. The footage was later debunked by Melbourne Airport.

However, his manager insisted to BuzzFeed News that the latest video was 'as real as it gets.'

Soledad O'Brien, who had a friend on the same flight as Saleh, tweeted that 'A LOT still unclear' about the incident 'nut apparently woman sitting near my friend tipped off flight attendants he was a youtube star known for pranks.'

'Also people on plane disputing call to mom,' she added.

Saleh has since defended himself to CBS News saying that he called his mother on every flight but this was the first time it had sparked such an uproar.

'I speak to my mom on the phone every flight,' Saleh said. 'She only speaks Arabic.'

He said when he was speaking to her, an American woman in front had turned around and told him he ought to speak English. When he replied he could speak whatever language he chose, the woman's husband began yelling, Saleh said.

That was when he and his friend were approached by the captain who asked them to leave, he claims.

During the footage, which has been seen more than 500,000 times since it was posted on Twitter, Saleh confronted the passengers who have made a complaint against him.

'I spoke a word and you said you feel uncomfortable. Why are you guys doing that?' he yelled at the men behind him.

'Just because I spoke a different language. We spoke a different language on the plane and now we're getting kicked out. This is 2016.

'Delta Airlines are kicking us out because we spoke a different language.

YOUTUBE PRANKSTER FAKED STREET ARREST OF MUSLIM... AND INFLAMED RACE RELATIONS Saleh apologized in 2014 after making a hoax video that falsely accused police of racism. He and friend Sheikh Akbar had claimed in a two-minute film titled Racial Profiling Experiment that they were singled out for abuse in New York because they were wearing traditional Islamic clothing. Hoax cideo: Saleh and friend Sheikh Akbar claimed in this two-minute film titled Racial Profiling Experiment that they were singled out for abuse in New York because they were wearing traditional Islamic clothing The video, below, showed the pair being shouted at by a 'policeman' as they walked past arguing, then were pushed against a wall and frisked. They claimed the 'officer' ignored them when they had the same argument in Western outfits. The video was picked up by media around the world as an example of police racism. The pranksters had to admit the hoax but their stunt angered American Muslims. Ibrahim Hooper, national communications director of the Council on American-Islamic Relations, said: 'Muslims are already under the microscope, and to do this just to gain some cheap publicity is totally unacceptable.'

'You guys are racist.'

In another video, filmed in the airport, Saleh says the incident ' made me feel like I was a terrorist'.

'Everyone was like, 'Kick him out!' All these racist people, I felt uncomfortable,' he said.

Saleh and his friend were marched off the flight and interviewed by police at the airport after the incident. However, neither were charged and they were both re-booked on another Delta flight home to New York City.

Saleh's spokesperson, based in London, told Buzzfeed that the whole thing began after an American passenger heard him speaking to his mother before take-off.

'He always speaks to his mum to get her blessings. As he was speaking, an American lady said she felt uncomfortable,' Saleh's spokesperson said.

'He's upset with the fact it's happened to him. He's in tears. We dress like them, we think we are like them. It's just a different skin color.'

Saleh has since been rebooked on another flight and is en-route to New York.

A HISTORY OF ADAM SALEH'S PLANE STUNTS YouTube star Adam Saleh shot to fame by pulling online prank, from his notoriously staged Racial Profiling Experiment to 'killer clown' pranks. But a favorite setting seems to be in airports and on planes, where he has filmed himself pulling 'pranks' seemingly aimed at sparking panic and fear, and others which would be downright illegal - if they weren't faked for views. JANUARY 13 2016 Saleh posted the video ' Arabs on a plane' in which he described how he was going to 'Arab fly' his friend, 'even though we are not going to an Arabic country'. In his 'Arabs on a plane' video, Saleh swapped his hat (left) for a Pakistani head scarf (right) to board the plane Once he boarded the plane, the 23-year-old swapped his his novelty beanie for a keffiyeh - a traditional scarf from Pakistan - which he wrapped round his head. 'Everyone looking at us thinking what the hell they wearing,' he said in the video. FEBRUARY 9 2016 Saleh pulled a similar stunt just one month later when he decided he would count down in Arabic while waiting for take-off on a flight from Chicago to Saudi Arabia. 'What would ever happen if we counted down on the plane, in Arabic?' His friend, who was on the flight with him, tried to dissuade him from doing the 'prank' which had the potential to spread panic and fear. 'No, bro, you wanna get kicked out bro,' his friend had replied. 'I can count down in Arabic,' Saleh retorted. 'It's asocial experiment, you know what I'm saying? He then began loudly counting down in Arabic, while his friend slouched down in his seat, covering his face with his hat. Despite the incendiary nature of the stunt, the only response they got was from a friendly passenger sitting behind who began chatting to the pair. FEBRUARY 9 2016 During that same video, titled 'Counting down in Arabic on a plane experiment!', Saleh had already decided to test the limits of airport security by trying to board a flight with a fake ID. The YouTube star, who was filming through Chicago's O'Hare Airport, admitted to camera that he'd acquired a fake ID in California and was planning to use it to get through security. 'I don't have my passport on me right now,' he said. ' I have this ID I have from California. It's not even a legit ID. It's a fake ID.' The stunt did not quite go as planned however, after the video cut to Saleh on the other side of airport security. 'They saw it and were like, look, this is fake ID and it's illegal to show it to government officials and the TSA so were going to call the police.' He said he was grilled by Chicago police who asked him to prove he was who he claimed to be, before he was finally allowed to board. DECEMBER 13 2016 On December 13, Saleh claimed that he flew from Melbourne to Sydney inside a suitcase (pictured) 'I'm Adam Saleh and I'm a professional idiot,' is how the prankster introduced himself during the video 'I sent myself to another country!!'. The footage made headlines after he claimed he'd squeezed into a tiny suitcase and illegally flew in the baggage hold from Melbourne to Sydney. Video showed Saleh's friends zipping him into a suitcase, wheeling him to the automated check-in area and paying the overweight fee, before the case disappeared down the conveyor belt. He can be heard saying: 'I am so scared, I don't know if I'm going to survive'. Saleh also had a camera inside the bag, and he could be seen sweating inside the tiny case. Melbourne Airport has since, thoroughly debunked the stunt as hoax, saying surveillance footage proves that Saleh boarded the flight normally. They also pointed to numerous flaws in the footage, including that Saleh would have exceed the maximum baggage weight. Melbourne Airport has since, thoroughly debunked the stunt as hoax Upon arrival in Sydney, Saleh climbed back into the suitcase, which his friends placed him on the luggage carousel before they filmed him climbing out of the bag, claiming he'd been there all along. 'While this video is clearly a publicity stunt, it promotes behaviors that are dangerous and life threatening,' Melbourne Airport warned. DECEMBER 21 Saleh films himself being ejected from a Delta Airlines flight from London Heathrow to New York. He claims he was kicked off 'after speaking Arabic to his mom' but many have questioned whether the move was yet another publicity stunt. Advertisement

He tweeted his thanks for his fans support, writing: 'I appreciate every single one of you!!!' and also warned that he would be speaking to his lawyers about the incident when he landed.

Delta Airlines confirmed that two passengers were removed from the flight 'after a disturbance in the cabin resulted in more than 20 customers expressing their discomfort.

'We're conducting a full review to understand what transpired,' a spokesman said.

'We are taking allegations of discrimination very seriously; our culture requires treating others with respect.'

Saleh shot to fame on YouTube in 2012 as internet prankster.

But he has been forced to admit that some of his most famous pranks were actually faked.

His most notorious hoax, the anti-police 'Racial Profiling Experiment', which was viewed more than 200,000 times, was so controversial it hit headlines worldwide.

In the video, Saleh and a friend arguing in front of a cop while dressed in Western clothes. The cop just ignores them.

Then the pair return in Islamic-style clothing and begin once more to argue in front of an uniformed police officer.

This time they are shouted at, pinned against a wall and frisked.

Saleh later admitted that the whole incident was staged, with an actor dressed as a policeman.

It caused fury among Muslim groups in the US who decried it as a 'cheap publicity' stunt by Saleh and warned that it would lead to genuine harassment being dismissed in future.

Last week, Saleh made headlines after he claimed he'd squeezed into a tiny suitcase and illegally flew in the baggage hold from Melbourne to Sydney.

Saleh later posted several videos from London Heathrow airport expressing his shock at his treatment

Saleh's videos have sparked outrage online where thousands have begun tweeting the star's #BoycottDelta hashtag

Video, posted on his channel, showed Saleh's friends zipping him into a suitcase, wheeling him to the automated check-in area and paying the overweight fee, before the case disappears down the conveyor belt.

He can be heard saying: 'I am so scared, I don't know if I'm going to survive'.

Melbourne Airport has since, thoroughly debunked the stunt as hoax, saying surveillance footage proves that Saleh boarded the flight normally.

Upon arrival in Sydney, Saleh climbed back into the suitcase, which his friends placed him on the luggage carousel before they filmed him climbing out of the bag, claiming he'd been there all along.

'While this video is clearly a publicity stunt, it promotes behaviors that are dangerous and life threatening,' Melbourne Airport told news.com.au.

Saleh has not commented on the airport's statement.
