Buchanan, who was the former host of children's United Kingdom program Art Attack, made a decision to clear up speculation after a social media rumour run rampant that he's the artist.
'The rumour that 90s/00s icon Neil Buhanan is Banksy is simultaenously the best and weirdest thing to happen in 2020.
They're churning the wheel on a conspiracy theory that has it that "Art Attack" presenter Neil Buchanan is the true identity of the political artist.
"We have been inundated with enquiries over the weekend regarding the current social media story", the note reads.
"Unfortunately this website does not have the infrastructure to answer all these enquiries individually".
'Neil spent lockdown with vulnerable members of his family and is now preparing to launch his new art collection in 2021.
Neil Buchanan, 58, is best known for his 17-year stint as the presenter of CITV's Art Attack programme and he also served as a presenter on ITV's Finders Keepers between 1991 and 1996.
"I'm not even going to look any further into this", one Twitter user wrote, "I'm taking this tweet at face value and telling everyone Neil Buchanan is Banksy now".
"This is straight in the believe without question category".
Banksy is a street artist based in England who has been active since the 1990s. "Thank you and please stay safe", it reads.
According to the thread, Banksy's art had been spotted in cities where Buchanan had travelled for work.
But the internet now believes someone else entirely could be responsible for the iconic pieces of graffiti - Neil Buchanan.
Various attempts to unmask Bansky whose most famous work includes Balloon Girl, Follow Your Dreams and London Underground Rats have been unsuccessful, with Robin Gunningham being the most commonly cited individual who could be the street artist.
A conspiracy theory that purports to reveal the true identity of secretive United Kingdom street artist Banksy has gone viral.
While commenting on the conspiracy theory, one woman noted that she had met the real Banksy at Notting Hill Arts Club in the late '90s, yet still wouldn't be able to recognise him in a line-up.
Banksy fans have even matched performance dates of Massive Attack with Banksy artwork appearing in cities.
The original poster replied: "So you wouldn't deny that it's Neil even though you've seen Banksy? Neil is Banksy, Banksy is Neil".
