A senior BBC staffer has ranted about the “holohoax” and called Jews “Nazi parasites” among scores of other antisemitic and conspiratorial messages on Facebook.

Dawn Queva, a schedule coordinator at BBC Three who has worked in children’s programming, is understood to be under investigation by the BBC over the posts, which date back years.

In a vile post on January 25, the BBC employee attacked "Nazi apartheid parasites who have zero right, historical connection to or blood ties to the land of Palestine."

Another of her messages appeared to peddle the conspiracy theory that the Rothschild family were behind the "holohoax", a term commonly used by Holocaust deniers to suggest the Nazi genocide was fabricated.

Other posts repeatedly attack white people, calling them a “virus” and “mutant invader species”.

On Friday Queva shared a video describing Jews as "very nasty” and “disgusting” alongside a remark that “the last comment sums it all up!” despite widespread reports that she was facing disciplinary action.

Queva, who writes on Facebook under the profile “Dawn Las Quevas-Allen”, appeared to want to face down criticism of her social media activity, telling her detractors on Friday: “Come at me by all means.”

In another post, she wrote: “It's not the land of the AshkeNazi, that is the German Rhineland. It is the land that belongs to the Palestinians. The Zionist genocidal land squatting so called ‘Jew’ irrespective of the fact that the UKKK and Amerikkka gave away land they had no god given right to a people who have no god given right to!”

In October, Queva wrote: “Karma is coming for the japhetic invader Israelis".

Employed at the BBC since January 2021, Queva previously worked for Sony, Disney and NBC.

Conspiratorial material has been shared on her profile for years and has included anti-vaccination conspiracy theories, as well as antisemitism.

In 2017 she wrote: “The Beeb is run by a bunch of JewISH Zionists who have been pushing Tory Politricks hard coming up to the next general election with the desired outcome of a One World Order”, Quevo wrote.

In 2014 she referred to Hollywood (or “Hollywierd”) as “another industry run by the FAKE JEW.”

In one post, she called on “Africa” to “kick the Jew right back across the Caucasus mountains to where they came from.”

A BBC Spokesperson said: "We don’t comment on individual members of staff and we have well-established and robust processes in place to handle such issues, we do not tolerate anti-Semitism, Islamophobia, or any form of abuse and we take any such allegations seriously and take appropriate disciplinary action wherever necessary.”

Queva was contacted for comment.
